You just discovered what competition is best for, in terms of practicing for self-defense. Because of its inherent limitations, competition is generally lousy for learning defensive tactics, and it's also often a detriment to mindset. But it is totally awesome
at helping people find and correct equipment deficiencies and firearms-handling habits which may otherwise distract, injure, or kill them in a real situation.
Practice! Practice! Practice!
Remember, though: it's not really how much
you practice, as it is what
you practice, that makes the difference. A dozen years of faithfully practicing the wrong thing can make you really really good at doing the wrong thing.
