It certainly beats talking shit on the internet and shooting at trash in the gravel pit.
The ability to shoot fast and accurately is never a bad thing. And if you can’t handle the stress of the clock in public, and some physical exertion degrades your marksmanship appreciably I don’t know how you’d expect to do well in combat.
If you get mentally defeated and can’t perform because you’re tired and sore on the clock how can you expect to do well in combat. if weather conditions destroy your will to win at an 4-8 hour match, how can you expect to maintain fighting mindset over the course of days, weeks, months? Watching peoples mindset and psychology degrade at matches under a mild amount of stress and perhaps public embarrassment is very enlightening.
