There's an older guy I shoot with who regularly, read every squad, flinches at least 3 times. He shoots between 20&23 but he sees 3-6 extra birds every squad than the rest of us. I know people can flinch once in a great while but I've often wondered if he isn't claiming to have flinched because he didn't like a particular bird. Should he be called on it? Should it be pointed out to the scorer or the guy who runs our trap program? What are the rules regarding something like this? Any information would be appreciated, thanks.
