Roger,
The sad thing is that I stood there for the better part of 40 minutes after the guns were handed out. Not one builder came up to me to ask about their gun and the critiques it may or may not have had. Or if I had judged it or if I know what judge had looked at it. And from what I understand it's not too common for individuals to come up and ask.
I personally reached out to a young man to discuss his carving and finish, but no one approached me.
Otherwise it seems as if most are more content to complain about the score, but do nothing to understand the reason. Heck we may look at something differently next year if someone were to show and explain something.
