20 pounder vs. T54's front hull

[Aeraaa]

In the game the 20 pounder's APDS shot has a penetration value of 30. While this is correct for armor sloped at 0 degrees from vertical, it is not the case for its performance vs. sloped armor. The frontal hull of T54/T55 is 20 IIRC, which is it's LOS thickness, but not its actual effective thickness vs. contemporary rounds. The result is that the 20 pounder can kill T54s frontally up to 1800 meters, while in reality it would struggle against the T54's hull armor even at very close ranges.

I think the gun's penetraton values should be corrected, as now it is as effective as the APDS of the L7 gun, the latter of which was made to combat the armor of T55.
