I'm aware of that. In figures it looks all verry nice but the feeling in battle is like nerfing. Dunno, maybe this is due also to penetration values that are different related to distance from target or because of t34 buff.... T34 and P4 are quite equal right now and thinking at production costs, I don't think P4 is as cost effective as T34 (phases, buildings and all). Panthers it's another thing, there are more opinions here they were overnerfed while quite expensive.
Umm, no, P4 and T34 are not even close to "quite equal".
T34 have less armor, longer reload and less penetration.
Its a 100% loss for it against P4, however it can win when it uses its speed to get behind P4.
Both are fine at the end, but they are definitely not equal.
You basically need to use the same amount of fuel as soviet did to counter soviet armor.
