Hi all,
a few months ago, I found the 'almost' exact formula for the research times in HoI2, I wanted to post it in the HoI2 wiki, but I was unable to modify the wiki. Asking in the forums, Altruist told me to post the formula in this forums, because several of you would find it very interesting. So there I go.
I did this several months ago already, so I do not remember all the details (in fact, I had to look at the formula into an excel spreadsheet I did with it and reworked it from there), and this might be a formula which had not the right modifiers for the rocket and nuclear research facilities, but I think this is the good one.
First of all, each research is divided into 5 'parts', this formula gives you the research time of each of those parts, in order to get the total research time, you need to add the 5 partial times. Second, this formula gives a fractional number, you will need to use the next whole integer in order to get the right number of days for each part, except if the difference with the previous integer is less than 0.01 (not sure if this one is the right difference, but I think it was this one), then you willl use the previous integer (this has to do with the limitation in the number of decimals the game can handle). Last, in the parts with double effort (or double level), mainly those which requires to build prototypes, you need to put the real lelvel of that part, not the one which shows up in the research pannel, but half of it.
Now comes a bit of 'what the hell means each thing':
T = research Time of that part of the research.
D = Double time, 2 if it is one of those parts which require of double time (or double effort, or whatever you want to call it), 1 if it is not.
Nr = Number of rocket or nuclear research facilities you have, if that part of the research is related to either rocket or nuclear science projects, if that part is not related with any of those, this number is 0.
Er = Extra research efficiency due to industrial research for tabualte and computing machines, if any.
Tl = Research team level.
Em = Extra research efficiency due to any minister, if any.
Dr = Dificulty level of that part of the research.
MF = Main Field research, 1 if it is NOT a Main Field research for the team, 0.5 if it is.
B = Blueprints, 1 if if u do NOT have a blueprint, 0.5 if you do have a blueprint.
And now comes the formula:
T = 100*D / [1.65*Nr + {(100+Er)*3*(6.1+Tl)} / {(100-Em)*(4+2*Dr)*MF*B}]
Hope you enjoy it, and hope to have put this post in the right place, xD.
Wanted to attach the spreadsheet with the formula, but is an xls, so I cannot
