Calculate the change of the Puma hitting and penetrating a Centaur and do the same for AEC (or even T-70/Stuart) vs Ostwind.(Want to check how Luch does vs centaur?)
I did it for you for armor. Won't do it for accuracy vs target size because my argument was that its durability comes mainly from target size. So your argument about hitting is invalid, because I never claimed that. I would approve my own statement by taking target size into account. I only claimed that armour adds little to its survivability because there are only some situations were it armor matters at all. Speed/accleration and armor of Ostwind would be plainly better in combination with Centaur target size.
vs Centaur:
Puma between 100%pen (close) and 50% (far) at 50 range / 120dmg
vs Ostwind:
AEC between 100%pen (close) and 73%(far) at 40 range / 120dmg
Stuart between 68%pen (close) and 50% (far) at 40 range / 80dmg
T-70 between 45% (close) and 36% (far) at 40 range / 40dmg
I don't see a problem, all cosr between 70 and 75 fuel (including side tech). AEC performs better with the exception of range. Puma still performs better than Stuart which is an AT source too if you look at its main gun AOE stats and its abilities. T-70 shoots a second faster than the other three but its performance is still way worse, because its main role is AI. It doesn't make sense to compare with Luchs, which is even cheaper and comes out earlier than these four. T-70 is really bad vs Ostwind already and will get destroyed by Ostwind pretty quickly. This is no problem of course since T-70 has lower cost and timing.
Armor does help Centaur it that simple vs a number of weapons.

which are rarely used vs Centaur or are meant to be AI with the exception of PZIV and maybe Puma at mid to long range.
-> corrected it for you. You don't have to give thanks to me :-)
