Close range infantry AT weapons.

[Fubar]

I've noticed in several recent games that involved German infantry at close ranges with enemy tanks that the mighty Panzerfaust isn't all it's cracked up to be. In one particular game i knocked out 4 T-34's at short range but all the kills were with the grenade bundle, the Panzerfausts either missed the target completely or failed to do anything at all, yet the grenade bundles seem far more accurate and each one when it hit killed the tank outright. I did put this down to luck but since then i've played several games with similar results, most notably on the Eastern Front. Does this mean that Panzerfausts are under modeled by the game engine, are grenade bundles over modeled or is it something to do with the dreaded abstraction of the games code and close assault ?
