Sunday was a very good day for our tournament. At noon, we had the meet and greet for the referee candidates (some have reffed for us before and are just brushing up, but some are very new to reffing). We exhaustively went over the rules, scoring scenarios, legal and illegal techniques for each division, and the refs scored two video matches on paper. Finally, it was time for live reffing. Every ref made mistakes, but rose to the occasion and learned a great deal from the clinic.
It doesn't get better than the six hours we spent on Sunday to prepare referees for the live experience of reffing.
