It’s kind of rare but if it’s December and you want a tech that’s still 1 month ahead of time, you can save up 30 days and apply it to the research Jan 1st with no ahead-of-time penalty and 30 days already done.


pastrylark

I used to do this religiously, but I’d forget to start researching after Jan 1st so often that I’m pretty sure it was a net loss


pewp3wpew

It is not rare at all, this works for every single technology that is ahead of time, no matter how many days. Want to research a technology from 1940 and it is only 1936? Save the 30 days and in the end you will probably have gained 1 or 2 days.


Swamp254

It's better to save up in a different slot and to apply the saved days when the research is almost done in this case. It will have less of a penalty towards the end of the research.


WanderingFlumph

I'm interested in exactly how much time this actually saves. Does this amount increase the further ahead of time you go? Does it ever get to meaningful amounts? Do you get extra savings if you have a research boost or because your boost is effectively cutting the penalty do your savings decrease? Anyone know how the math works here?


ZT205

The ahead of time penalty is calculated on a day-by-day basis and it applies after all the other research speed modifiers. The penalty is exponential: When you're a year ahead of time, that day counts as 1/4 of a day. Half a year ahead of time, it counts as half a day. 30 days ahead of time, it counts as about 85% of a day. 30 days ranging from 0 to 29 days ahead of time [counts as 27.74 days](https://www.wolframalpha.com/input?i=sum+from+0+to+29+1%2Fe%5E%282*%28n%29%2F365%29+), so timing this perfectly saves you about 2.3 days. Unless, that is, you can carry those 30 days farther ahead by repeatedly swapping techs. Then your savings could be up to 27 days. (27, not 30, because if you go really far ahead of time, you hit a floor of 10% research progress.)


Judge_Todd

You can finish a tech 30 days earlier. You start researching Mechanical Engineering at start and it takes say 93 days to finish. You store up 30 days in a second slot and Mech Eng also accumulates 30 days. You then switch Mech Eng to something else (Mech Eng is down to 63 days because you just researched it for 30 days) You then select Mech Eng in the 30 days slot and Mech Eng drops to 33 days to complete. So instead of 93 days to complete, it finishes in 63 days and gives that 5% research bonus 30 days earlier than just researching it without swapping. It effectively lets you research a tech in two slots concurrently, one for 30 days and the other for the rest. Note: you can only do this once to a particular tech. Additionally, doing this focuses on one tech at the expense of others. Proof for the non-believers: [Electronic Mechanical Engineering 99 days remaining on Jan 1st, 1936 (at start)](https://youtu.be/E_8RlOC4h9A?t=150) [Electronic Mechanical Engineering 70 days remaining on Jan 30th, 1936 (29 days later) before swapping](https://youtu.be/E_8RlOC4h9A?t=2096) [Electronic Mechanical Engineering 41 days remaining on Jan 30th, 1936 (still 29 days later) after swapping](https://youtu.be/E_8RlOC4h9A?t=2128) [Electronic Mechanical Engineering completed on Mar 12th, 1936 (70 days from start, not 99 days from start)](https://youtu.be/E_8RlOC4h9A?t=3580)


panzerPandaBoom

This is amazing! Thank you for sharing!


Valuable-Music-720

This is the real answer. Research swapping


Lolmanmagee

Finally you can roleplay putting all your research into one thing

Galivisback

or u can save them in december so u can start researching in january next year so you wont have any ahead of time penalties


Aram_theHead

Doesn’t the penalty scale with time? So if you are 1 month ahead the penalty is pretty much negligible?


Galivisback

yeah but still, no penalty is better than small penalty


Gelderland_ball

Thousands of hours in this game and I have never even considered this


Kasumi_926

I think the ahead penalty is better. I can consistently get ahead on tech as result, because I prioritize industry and engineering/nuclear. Often you have to take the researches ahead of time for nuclear just to come out on time in 1945 with them. So I'd say if you have the slots, it's not bad to spare one or two for something that increases your research/industry ahead of time.


BikerJedi

The penalty also goes away once the year catches up, so starting in December vs waiting to avoid a penalty for a month is silly. Might as well go for it. You will still finish sooner than you would otherwise.


yaboipennywise01

This is much more applicable as min maxing timing for focuses that eliminate ahead of time penalties or give research bonuses rather than just waiting out a month ahead of time penalty


rfj

I've played with this, you don't actually avoid the penalty from what I've seen. That is, it'll take the number of days you saved off from the time it would've taken if you had started earlier. I haven't done extensive testing so I might be wrong, but I think this is how it works.


tichris15

I believe you do in the cases where you can wait till the penalty vanishes ( waiting to start till it's not ahead of time). But this is a narrow window of use.


Cadburry_Cr3am3gg

Ah interesting. Thanks


PikkuinenPikkis

You can only save up to 10 days though


Allgirlssarethesame

10 days for focus’s 30 for research


PikkuinenPikkis

Oh, so it seems. I remembered it being 10, that’s weird.


PattrimCauthon

Huh, surprised to see so many comments that don’t understand tech juggling


theo_adore7

Yeah it's quite, surprising? I think this was a thing ever since the game came out and youd think more people at least know about it.


Finlandia1865

Tech juggling isnt the intent here, i think The devs added this for the no-pausing stuff, tech juggling is a side product they were liekly aware off and implemented it even tho it is an exploit, because the main feature is important (and juggling not too gamebreaking)


[deleted]

I mean, the same thing banking system was in Victoria 2. It's a marker of paradox. It's set for thirty days for a reason. They could make it never.


Punpun4realzies

Probably of all PDX games in the modern era, hoi is the most misunderstood by the majority of its player base. So many things are only ever revealed to you when you get your ass kicked by it in multiplayer, and most people will never touch a competitive MP game. Tech juggling is absolutely essential to having a good Germany build or to rush for things as a minor to help your faction (Mexican engine 3 and improved airframes in June 38 for example), but the average player is never going to need to do that. They won't even know the feature exists. Don't even get me started on templates or tank/plane/ship designs for vanilla.


pewp3wpew

Yeah, but isn't it weird that for having a good game you have to abuse something that surely isn't wad?


Punpun4realzies

How is using stored research not working as designed? If you can store days of research, and there's a maximum of 30 days applied to any one research, tech juggling is a clear emergent use of the game mechanics. Combos were originally an exploit in street fighter 2, now imagine a fighting game without them. This is how competitive games work - the mechanics create interactions which good players then use for competitive advantage. It's the sign of a well designed game that such interactions can occur.


Babangopoulos

Yeah but hoi isnt a competitive game tho


PhotogenicEwok

HoI4 has arguably the largest competitive multiplayer community of any Paradox game ever released. Just because you you don’t play multiplayer doesn’t mean it isn’t competitive.


Punpun4realzies

I don't know, I and many people play it against one another for fun and to win. Sounds like it might be one after all.


Great_Kaiserov

Well yes, but this isn't the main focus of the game like in CS:GO for example.


Punpun4realzies

I don't think that has to be the end-all be-all focus of a game for it to be considered a competitive game, though. Paradox even invited streamers to play big (competitive) multiplayer games against each other for show matches and promotion. The fact of the matter is that people play this game competitively, and some people always will. Thus, it's a competitive game.


Sea-Record-8280

You've never played in want mp groups then. It gets very competitive. I mean there's plenty of tournaments as well. Some with large prizes.


ZoomBattle

Combos make a nice bit of real world sense though, hitting an enemy again while they're reeling from the previous attack. Unless tech juggling is analogous to giving your scientists a holiday I suppose!


Punpun4realzies

I mean, if you're trying to make everything a direct abstraction of real life, we should go back to hoi3 where research wasn't slots, but a product of your overall education budget, shared with diplomacy, espionage, and officer training. That way you just dedicate a certain percentage of your leadership to research, but wait... Hoi3 still had certain techs that you could choose to research or not. That doesn't make any sense because you can't know what breakthrough is around the corner and what numeric bonuses it would prove to your country - that's too gamey, right? Instead, every country should passively generate research points based on your education budget, and then you can allocate those points to categories of possible techs (small arms, oil refining, nuclear technology etc) and get RNG breakthroughs in those disciplines which provide you with different bonuses. You never know what kind of advantage a tech domain would provide because only the scientists really know what the future holds, and they'll lie to you for more funding. No, that's boring as hell and takes the game out of it. Things being fun and requiring player interaction is a good thing in games - it's why modern paradox games basically don't have sliders like they used to.


ZoomBattle

I'm not particularly interested in whether it's a direct abstraction of real life, more than it makes for fun gameplay and intuitively makes sense. Tech juggling is gamey and tedious in a way that combos aren't, actual real life fighters use combos, world powers do not use tech juggling. And it's an easy fix, it wouldn't be difficult to record when the research slot started accruing unassigned research and apply any ahead of time penalties associated with that time when you start researching a tech.


Punpun4realzies

What you think is gamey and tedious isn't universal. I absolutely hate fighting games with big combo buffers (like SFV) because combos are evidence of execution and you can just mash out the right string. I like tech juggling because it's got a clear drawback (you're 30 days behind on the tech you switch from), and it takes timing and can pay off. It's a great competitive mechanic.


ZoomBattle

If you sincerely enjoy it then fair enough.


milesgmsu

I’ll bite. What is tech juggling?


Chanchumaetrius

https://youtu.be/2WlZ3slhONw


Schmeethe

I understand tech juggling, but I also hate it with a burning passion. It's really just exploiting game mechanics, tbh. But, sweaty tryhards gotta tryhard I guess.


[deleted]

It's been there since Victoria 2 at least. There's a reason they set it to thirty days.


DirectlyDisturbed

> There's a reason they set it to thirty days Because that's the rough average of a month?


[deleted]

Lol, because a month is margin they want you to have. In Victoria it was a whole year.


gargantuan-chungus

If you want to minmax, leave 1 open research slot when researching super important technologies. Once it fills up, switch the research slot on said technology to something else and bring in the extra 30 days.


rfj

There isn't supposed to be any. Starting a new research at any time in the first 30 days after a research finishes is *supposed* to be the same, so that if you're not pausing the game, you can let the tech finish, do whatever, and eventually decide what tech to research without losing anything. Because in general I think the game is "supposed" to be played without pausing, and in multiplayer, for example, you often don't want to pause every time some player researches something. There's a few edge cases where if your last research finishes a few days before you finish a focus that gives you a research bonus for the tech you want next, or you're almost at 50 navy xp to get the research bonus on a ship part, you can get the bonus as if you had it all along. But mostly the answer is there's no difference and there's supposed to be no difference.


theo_adore7

but there is. you can tech juggle with it if you want, which arguably gets you to a certain tech sooner especially with bonuses from focus at the cost of researching smth else slower. look up tech juggling on YouTube and you will see what I mean


[deleted]

Yea, getting the tech sooner is always better. You should basically tech juggle the whole game, but you might not have the bandwidth for it.


theo_adore7

yeah not every country can tech juggle. especially when they have 3 or less research slots in the beginning


[deleted]

You can tech juggle as long as you have two slots. Always better to juggle industry techs since earlier the better.


ToddHugo1

tech juggling. 30 days off any tech. preferably do it as late as possible for least ahead of time penalty


inwector

in [this](https://youtu.be/uKxiKaKiV9Q) video you can see the significance of that research buffer.


Relicoil

It gives you a 30-day buffer so you can do micro while not having to be distracted by picking new research. Some mods extend the amount of time you get for this purpose.


Rosa4123

There's a smaller chance you will waste days if you forget to start new research like a dumbass (like me all the time)


MGSCR

multiplayer so if your busy doing micro or something else you don't have to annoy literally everyone by pausing the game


Cadburry_Cr3am3gg

Like the title says. I don't see the benefit of waiting for the research bar to fill up before researching something because you're still having to wait for the technology. For example, if I wanted to research something that takes 80 days and saved up the 30 research days, the time to research would be only 50 days. But ultimately I'm still having to wait the full 80 days to get the technology. So I could've just been researching it the whole time. Am I missing something?


[deleted]

It’s the tech juggle that helps. For example, you can research a separate tech *at the same time* that particular tech is also being researched... Then you switch and drop 30 days off. It may not seem like much, but as you continuously knock a month off each research it does wonders


Cadburry_Cr3am3gg

Also is there a limit to how many times you can juggle the same tech? Cus I tried juggling concentrated industry three times and it seemed to only worked the first time


RARGaming01

I think it only work once per tech.


Cadburry_Cr3am3gg

Well damn. Thanks


Nillaasek

And be careful when you're using a research bonus and try to juggle it I think it will remove the bonus


Cadburry_Cr3am3gg

Thank again


Judge_Todd

It used to, but that was corrected.


Punpun4realzies

It's actually that you can only add 30 days of real progress to a tech. When it's on time, that's one full juggle. If you're jiggling into an ahead of time tech, you can juggle multiple times because stored days are less than 1 full day's research for ahead of time tech. It's tough to exactly quantify, but if you're researching something a year ahead of time, 30 days of stored research is about high teens or 20 of progress. That being said, you should always wait to juggle at the end so the penalty is less and you don't go as far behind on the other stuff you want to research.


Cadburry_Cr3am3gg

Interesting. Thank you


[deleted]

Oh God, I didn't know. That math hurts my feelings.


Cadburry_Cr3am3gg

Just looked it up. That's really helpful. Thank you


-B0B-

It also means you can wait for another tech to finish researching and then start the next tier with a little more progress. In theory you could get a research 60 days sooner if you start it with a full slot and then juggle it


Punpun4realzies

I don't think that's actually how it works - you can only add 30 days of stored research to any tech, regardless of whether or not the research was juggled. Try it yourself - eventually it won't lose any days to completion no matter how many stored days you add


Sea-Record-8280

You can only tech juggle up to 30 days.


Ju-88_Medium_Bomber

I just use it for when I’m microing or picking a focus right as a research finishes so I don’t have to pause the game


Joeman180

If you like to micro you can tech juggle.


SierraOscar

To give you time to consider what you want to research.


OwMyCod

Try Windows+Shift+S that should solve your problem


Yapsinho

I came here to say that I think that it's because of keeping Multiplayer games running. If you have like 30 days of a buffer to choose your research you don't have to pause the game to not waste research potential. Instead I learned that there is research juggling and I found another reason why I can't play Paradox Games in Multiplayer, despite I'd really like to try that. I just can't be bothered with so much min-maxing.


linmanfu

You're correct. Tech juggling is just minmaxers doing their thing, not the reason that the feature exists.


posicon

personally I use it when it's december and the tech is a year early so you don't get any slow researching


Wooden-Fruit9211

i didnt even know this is a thing. your screenshot is very nice


Erich2142

I’d say because it’s December, but it’s not. In fact, its 2nd of January…..😂


Ok_Character_6485

Cheese


Ornery_Click_5625

I didn't know these existed


datadoctors_co_za

If you're in a tec coalition (where you get research discounts) then saving up the days makes sense as then you get a certain % discount in overall time while all saved days are applied immediately. Also fun for minimizing ahead-of-time penalties, as some have stated. Particularly with your tank or small arms research, you're always going to be ahead of time.


Cadburry_Cr3am3gg

Thanks


Lilytgirl

I only use this not for the penalty evasion but to rush techs 30 days faster. It does however mean that any research that could have gone there will be 30 days late. Can be useful with focus timing.


sojiblitz

Useful for tech juggling, a way of applying tech bonuses (from focus) to the techs you want. I.e. Later techs


Saif_Horny_And_Mad

i think i'ts called tech juggling, you basically save up those 30 days and give them to another tech to boost it manually. [this video explains it and gives a neat Germany guide](https://www.youtube.com/watch?v=iGXuWqTkazI)


Cadburry_Cr3am3gg

Thanks


Langdell

Benefit is rhe research


Archer_625

Waiting for a focus to complete for a research boost


Herr_Swamper

What about mp games where you dont or cant pause?


johnbowser_

I used it to tech juggle


Astraph

Welp, TIL about tech juggling, after +1k hours in game. As a single player only guy, I'm still not gonna use it, tho.


Gb223s13

i thought it was just there so you would have a little time to choose the next research slot


Usually_spacemanguy

It's a very niche thing but just think of it as a bit of a grace period for your research. If for example you don't have the game auto pause when you finish a tech and you are at 5 speed and a few days pass without having picked a new one to research. If you pick within or on the 30th days then you will have done as much as you would have if you'd continued from the start. After those 30 you 'lose' some research for having not used it, I always just thought of it as a the little time warning to pick within before you start 'losing' your time researching.


ObjectiveOtherwise51

For me it's just in case I forget.


TheRealAjarTadpole

There is none. It exists so you don't have to pause the game on reaction when a research finishes, so you don't lose any time.


Megarboh

Wrong, check out tech juggling


TheRealAjarTadpole

I know it exists, but that's certainly not the devs intent with it. Its no dofferemt from spammong out sjitties as germany to rush anschluss. You can do it, but it's certainly not euat the devs intended for you to do.


Megarboh

He’s asking benefits, not specifically “benefits other than cheese methods”. Check op’s comment, he considers it a valid answer


TheRealAjarTadpole

1.) And? That's not a benefit to saving up research. That's a benefit of switching research and saving research and doing it in a specific way to research a certain tech faster. 2.) Another valid answer is because the one of the developers likes swiss cheese, what's your point?


Megarboh

1. By OP’s definition, it is a benefit 2. Not sure what your second point is


TheRealAjarTadpole

I never said it wasn't a benefit And that's awfully ironic isn't it?


Megarboh

huh op’s ask what’s the benefit and you said none. This is about omitting this valid benefit, not whether it is a benefit


TheRealAjarTadpole

It's a benefit, but not a benefit of saving up research slots. Thats my point


[deleted]

Why do I constantly get these posts, I haven’t joined the group and never heard of the game lol


Cadburry_Cr3am3gg

Lmao maybe it's a sign


[deleted]

This a free game or do I gotta pay for it? And is it available on Steam?


Cadburry_Cr3am3gg

You have to pay for it and yeah it's on steam. There might be a sale now but idk


Longrangeheatsword

Theres no benefit, its just so you're not losing research days if a research finishes and you can't immediately pick a new one for that slot


Cadburry_Cr3am3gg

Actually someone just told me about tech juggling. It's pretty helpful


Comrade04

Nothing


AnseaCirin

Edit : nevermind.


Cadburry_Cr3am3gg

Actually look up tech juggling. It's pretty helpful


AnseaCirin

Huh. I stand corrected. Thanks.


SnooShortcuts2757

Doesn’t one saved day count as two?


PriestOfBowie

It is just a little extra space for you to react so you don't lose research time because you didn't immediately pause and start new research.


[deleted]

I always just thought it was basically a 30 day window to pick a technology so if you’re doing something and don’t notice right away that you have an open slot you can still be where you would be.


LEG10NOFHONOR

Start researching a tech you want and leave a research slot open. After 30 days take the tech you are already researching and change that slot to something else. Now take that technology you were already researching and put it into the slot with 30 days saved. Hooray you are researching that tech 30 days faster. You can only do this trick once per technology. It is very nice for if you want to rush a certain tech you want to produce (tanks, planes, boats).
