maximum range vs weapon accuracy; warhead vs penetration

[jivemi]

Armor Pen Calculator can be accessed by clicking on the Utilities tab in the game startup window. RPGs fire HEAT warheads which like AP and APCR (or Sabot) can sometimes achieve penetration higher than their normal rating. Hence each category (AP, Sabot, HEAT and HE) have one row of figures for normal and another for "best" at various ranges. Dunno about the effect, if any, of max range on accuracy.
