NOW ITS ON YOU! Look how easily the panther die to the shot from churchs..which penetrate on even far range!!
Probability of single Penetration was alread explained to you.
As I have said, that is extremely unlikely Event and since you did not gave any time stamp and I do not have time to watch the whole Thing, only instances I cought a glimpse where panther lost hp against Churchill was when there was ATG and/or firefly involved as well.
I also find it hilarious how you try to talk about penetration stats when you are not even aware of the values or how penetration works at all.
The probability of 3 shots penetrating panther frontal armor in row is 3%.
The probability of 4 shots penetrating panther frontal armor in row by Churchill at max range is 1%.
Source; Basic math
Do you see how unlucky you have to be to get multiple penetrations from Churchill frontally?
