"Shooting at high speed doesn't come from moving fast as much as it comes from economy of motion" -- this from one of two Danish shooters (can't remember which) who have taught me a lot about the mental part of shooting.
There's a reason that "DVC" isn't "VDC" or "CDV". Accuracy, Speed, and Power: that is the proper sequence. If we could add another letter to DVC, that touches on the equipment we use, it should be whatever the first letter of the Latin word for "reliability" is (anybody...? Howd'ya say that in Latin?). Shooting a match and not having to give up a single brainwave to thoughts like, "What if my gun chokes?" is a valuable confidence booster. Knowing that your pistol is very accurate, or, at least, knowing how accurate it is, just exactly what it can and will do, is an incredible help also. Have read an awful lot of articles in the gun mags about "combat accuracy", what's good enough, each author's opinion on how much will do and how much is not really needed at the XX feet (insert favorite expert's statistic) distance of your average scenario.... some of them even seem to imply that more would not be beneficial. Dang, some almost seem to imply that you're a sissy if your 1911 groups well at 50 yards, and that to regain your manhood you should take a Dremel and grind until your groups open up! I figure there's no harm in being able to ding a popper at 100 yards, especially since the days of thinking we must choose between accuracy OR reliability are long over.
