Elaborate on what?
Not ALL folks who are into competition are in it for pure competition/score. Some are in it for improvement of skill overall. You should try it. . . it might open your eyes to some things. . .
A competitive situation is important when training for the real thing. You're under pressure to hit the target in an area that scores points, you're under a time crunch, depending on the stage you may be using barricades, obstacles, moving targets and other challenges, and you have a bunch of people watching how you do. All that, and you have to be careful of safety rules such as being aware of muzzle direction, safely drawing from holster, and above all not dropping your firearm.
Anyone can practice on a target range and meet high standards with enough practice, but that can change when you have to move, fire at moving targets, perform reloads, fire from behind cover, shoot through small openings, and do it all as fast as possible while following safety rules.
The problem I saw with MPPL competitions was the lack of trigger time. Most of the time was spent watching everyone else shoot and helping reset or tape targets. Maybe 15-20 minutes of shooting out of several hours standing in the midday sunshine trying to stay hydrated.
if they could have split us up into smaller groups among more stages running simultaneously, I would have continued going.
