So, I wound up arriving two hours early (and four hours before my first match) to get pinned once and thrown once, thereby eliminated from the game in two rounds.
Of course, it was a two-man division, so I still got second- against a blue belt who weighs 15 lbs. more than I do.
More fun than the actual competition was my helping score the other matches. After I was eliminated, I headed over to the scoring area where they had to make do with three people (it really takes four to run the scoreboard and stopwatches) to score the remaining matches- and wound up being asked to stay to score the senior division. So I hung around, it was quite fun to watch!
Probably the funniest part was a comment from a referee as we began the senior division; he told us a few changed rules, and one final comment based on a few jokes we had made about the "5-year-old girls" division in the tournament: "And in the senior section, there is no 'cute-and-fuzzy' division."
I was informed at the end that I did even better with the scoring than I did last time- the referees came over to thank us for the help. We didn't screw up much- and when we did, we fixed it without a fight. We showed when we weren't certain who just won a point instead of guessing, and overall it ran smoothly- we were informed at the end that our fixing our blunders without argument or incident is the exception rather than the rule? They're the referees who have been at it for decades, why would we disagree?
The referees didn't know why they were so often fought, but they appreciated our compliance- overall, it went well. And I had fun.
