I'll add as upgrades:
OH: bunker + medics
USF: ambulance
SU: medics
UKF: MAYBE the medkit upgrade but that doesn't affect teching
I didn't include healing as that's pretty subjective. And factoring munitions costs is pointless cause munitions don't have predictable expenditure patterns unlike fuel and mp. (I.e. cannot equate munitions to time unlike fuel and mp)
if enough members agree though I will add in these costs but then there will be complaints of distortion.
The idea is you can use this to figure out windows of time by comparison of the 'first' unit costs e.g. UKF can build first centaur before first stug by skipping all upgrades. The difference is approx. 20-30 fuel. So translates to a approx. 1 minute stug-free window and hence plan accordingly. Planning on P4 while UKF skips all upgrades is a bad idea cause the fuel difference goes up to 60ish so 3 minute window roughly.
Conversely if UKF goes all upgrades you can see that ost player can comfortably get P4 by the time centaur or cromwell are built. That sort of thing.
