If you dramatically outperform your handicap it's generally presumed that you have been "sandbagging" which is a form of cheating.
The average comes from the average of the shooter's four HIGHEST scores, not his overall average score....someone with an honest 270 average...
People do that kind of thing. Yes, it only works for a little while....someone would have to intentionally shoot poorly for at least four matches to set up the high handicap, then start shooting well to "cash in" (which would then lower their handicap because the higher scores would substitute for some of the sandbagging low scores).
Yes, a lose. This does not happen very often. If it does, its a new shooter that has picked there first H'C, making it to high. After they get there 4 highest scores for an average, its not likely to happen. The shooter that improves each month has a slight advantage over a constant shooter. A high master is still top dog, but can be beaten. Example >Maybe I don't understand what you're saying, but why would scores over 300 lose? Let's say a shooter has a 270 average, so he gets +20 points as his handicap. He has a good night and shoots a 281, which is easily possible for someone with a 270 average, and ends up with a 301. Are you saying he loses?
The NRA Bullseye rule book is used to break ties or if shooters agree a flip of the coin. The range office can compete if the timed & rapid commands are recorded/played.If 300 is the max. score, wouldn't any ties then just be settled on X-count?
