"even as small as it is, has a chance to bounce the JP means that its armour is pretty impressive (i was under the impression that small chances to pen were null but any chance to bounce was untouched, as small as it is)"
Small chances ARE NULL JP4 won't bounce anything from su 85
"And being able to bounce mediums more often than not IS a big deal when we are talking the prices were talking for these units."
Generalist mid pen is 120.
It means 53% of penetration chances, hardly more often than not.
What generalists are you looking at here? Iirc the only medium with pen that puts mid pen at 120 would be the sherman AP shells (140 close iirc) t34 should has 100 mid (80 at far) and the cromwell should iirc have a profile no better than the old p4 (100/110/120)
E8 and t34/85 have better profiles of course but they are doctrinal and much closer in price
As for the null deal there on stats, im not sure the chance is negated that low. Perhaps Vipper could confirm/deny but i thought it was a much lower margin (like 4% or lower) to count as negated.
