Question is, did all the shooters you have listed shoot from the the same stakes, the same course and under the same rules going in as the rest of the competitors, was the 10ring the same size for all and was the 11 ring the same. The game is the game and hunting is hunting. The 11s are not a gift, but a combination of skill and some luck. The game has changed and the person that is winning is not winning because he has not earned it.
The people at the top of each class want to stay there, so if you are going to beat them do it with your bow not the rule book.
