Frankly, the really good shooters in USPSA are actually pretty modest about their accomplishments. The GM in question got his card legitimately, has been in the Top 20 a number of times, and has paid his dues. Seems like a decent guy, too. He deserves to be treated better, whatever level he's shooting these days.
BTW, this GM was in the top 8% of 230 at Iron Sights Nats last year and grouped with the other GMs. If he still shoots at that level (say, 80% of #1), a 74% performance in the recent local match against him was actually about 59%. Not bad, but lots of work to do.
