Besides agreeing to some suggestions, I don't have much to add to this. As David suggested, it seems clear that we have to emphasise and enforce WCA regulations 1e2 and 1f2.
We do need to factor in the amount of new cubers attending this competition. In the first rounds of 2x2 and 3x3, I judged a number of competitors who wanted a quick walk-through of an official solve. I don't blame them for lacking the confidence to volunteer judging. After lunch, many of these new cubers stepped forward to give a hand, that was much appreciated.
On a side note, the venue was great and everyone was really friendly as usual.
Hmm, I'll try to think of some DYKs that haven't been mentioned. DYK...
-I didn't expect 5x5 to be so competitive?
-Toast's shirt had '43,252,003,274,489,856,000' wrote on it?
-team BLD step-solves with Aron are fun... except when there is parity?
-the security alarm went off, luckily it was during the break between 3x3 final and awards?
-Luke did an awesome job with the photography?
-Tim McMahon + mo = one creepy photo?
-actually, several creepy photos?
