Nope, all the votes are legit. If you voted before the change, it will show your vote in the wrong category in italics, but that's different logic and it doesn't affect the numbers.
I'm not surprised. I've seen lots of people at ECES/SES and other smaller gatherings that I would call Masters. I've also seen some WC types that weren't any better at freecarving, so I don't think we need lots of levels between MF and WC/O. Just because you race doesn't automatically mean you're a superior freecarver. I've seen a few examples of people who raced and didn't even know how to carve a "C" in the snow.
D-Sub is soapboxing just for the sake of it. This is an anonymous poll, so nobody's tooting their own horn here.
