you can calc like this..yes,,,but this isn a realistic calc for the ingame. ingame its actually pretty normal to get 4 sections. and its normal to get 1-2 obers. so lets be near to the realistic scenario. and than u dont pay all this upgrades only for one section. u pay it for mostly 3 or 4 or even more. but obers? how many of them you have at the same time? mostly only 2. so my calc is more realistic and than all other "calculations"
No, your calculation is - at best - naively misrepresenting the actual game.
The only way your calculation were correct is if you paid all these resources just to get Obersoldaten with LMGs. But you do not. These resources get you to that point, but they also get you teching to all tanks that OKW can get.
If you really want to insist on your calcs and move all the costs to Obersoldaten, then OKW would also pay only the 350 MP / 140 FU for their medium (since all teching costs already have been allocated to Obersoldaten), while UKF still has to pay for their Cromwell PLUS their whole teching costs (somewhere around 265 FU if I am not mistaken). Now explain to me why my Cromwell costs almost twice the amount of fuel while it is shittier in almost every regard? Why do I as UKF pay fuel in the range of a heavy tank for a medium?
See, this is the same argument you (and also Katitof) are using for Obersoldaten and IS. They are all strawmen arguments and completely miss the point of the whole discussion.
The only point you can make with "adding" all the tech costs to Obersoldaten is that they come way later than infantry sections. But you did not. Not a single time.
