weapon 61 has warhead 44 - an obvious error that contributes to the penetration. Likely a double tap of 4, many years ago. Something to fix for the next release.

HEAT (and AP) are an average of 1000 shots per range bucket. HEAT is very variable - look at best HEAT as an example (best shot of the sample of 1000). HEAT can use fail or not fully develop, especially WW2 vs MBT HEAT ammo, and in rare cases can over penetrate. So a reliable figure of 4 for that weapon is well within the bounds.
