Well, Chuck, how about I've been counting patterns for about 50 years or better and I've never seen a 30% pattern out of a full choke barrel but I've seen people that couldn't hit the pattern board or count or do simple math. I'd much prefer to vote for one of the two later possibilities after 50 years of empirical experience shooting a shotgun. I think I could throw a 30% pattern with my hands, no shotgun. OK, that's an exaggeration, but not by much.
