Be careful judging others based on your own experiences and abilities. As a 40 year BR shooter, I have shot and witnessed way too many of those in 5 and even 10 shot aggregates, so there are several people who would take your $100.
If you wish to improve at any sport, go compete with the champions and listen, watch, question and learn. However like any sport, one may or may not be able to someday achieve what others have. As a youth, I played basketball and football, but there was no way I was ever going to make pro. Same with golf.
I have competed in varied shooting competitions for 4 decades National Match, BR, Palma, 1,000BR, etc, and regardless of years spent, very few make it into the top ranks.
