Minor quibble:
Snipers and long range target shooters establish a baseline zero and then adjust their sights off of that based on variables like the wind. As the author correctly notes they learn how to make those adjustments by missing.
They learn how to make their bodies perform both by missing and by practicing a lot; a large fraction of those "5,000 shots in training" will be something better than "misses" if they're going to be successful in the field or competition.
Lesson for this domain:
Learning how to do some things reliably on demand is also a part of being generally successful (it's at least one foundation) and for almost all that takes plenty of practice.
