	For example, some helpful people have pointed out that it's probably incorrect to consider ammo capacity limitations on the rate of fire when looking at the "instantaneous" value. So the "instantaneous" firepower of single shot weapons is understated in these tables. I will put a note to update my spreadsheet and recalculate.

For "instantaneous" values, this can have decimals/fractions, as it is an "instantaneous rate" (as in calculus).

Real situations are mostly between these two extremes.		As noted in the text, there is no account of near misses from area weapons. "Shock" assumes <b>everything</b> hits.

	Could you explain further what Instataneous rate and sustained rate mean? Give the formula or something? Some of those figures look wrong, specifically the Rocket Launcher.
