Unclenick, that is the best "layman" description of the statistical effects of given ammo variables on accuracy that I have ever read. No one I know that understands it as well as you has the patience to explain it anywhere near that concisely!

Excellent summary. If you're shooting something like IDPA against the clock, with a flash sight picture on iron sights out to about 25 yards on an 8" diameter A zone, then the absolute accuracy of each round (given reasonably consistent loads) is insignificant compared to the other variables.
