KV1 has 800 health with 10% damage reduction if I'm not mistaken. That makes it 889 effective health or 6 shots to kill (5 shots plus snare is not sufficient). At this point I have to correct myself, since I forgot to account for the unique damage reduction.
At range 40 KV1 needs 11,7 hitting shots to kill an OKW P4 and 9,0 hits to kill OST P4, while both P4s need 14,73 (all pen corrected). Accuracy is similar on both with the KV1 being hit slightly more often due to higher target size. Not sure about the scatters though. Close ranges favor the KV1 more than the P4s.
Reload times are pretty much the same, not sure about other factors, since ROF is pretty complicated to calculate.
20 % not 10 it has 0.8 reduced damage
To give the KV-1 a more defined role as a breakthrough unit, we are slightly increasing its durability, and significantly increasing the rate at which it can get repaired. The following changes will result in KV-1’s being 25% faster to repair.
Now has a 0.8 received damage modifier
