I actually think a lot of people end up with too many matches, as weird as that sounds.
I know everyone defaults to more matches = better experience, but I think a lot of that is because everyone has been one and done before and knows how much that sucks. But after a certain point, you just start to get tired.
I did one of their tournaments and was scheduled for six matches. For my sixth match, my opponent just refused to compete anymore. I think it was like his ninth match for the day, and he said he was just too tired for another one. Also we had already had two matches against each other prior already that same day.
If you happen to have a bad day, it also turns bad day into a horrific one. That happened to one of my white belt students. It was his first tournament, and I think the nerves just got to him. I could tell early on that something was off and he was having a bad day.
He did gi and no gi in full divisions, thus having eight matches. He went 0-8 on the day. He brought his parents and his girlfriend to watch his first tournament. I could tell he was seriously embarrassed in front of them. I thought he was probably going to quit after it actually. He did not quit outright but has been training a lot less since then even though I did my best to give him a pep talk to stay positive about the learning experience. I haven't seen him in over a month now.
So yeah I guess I kind of wish that they went with double elimination or something vs the crazy high amount of matches they put together with the round robin. Four matches on the day seems about right to me. The 8-10 that some people end up getting is kind of nuts I think.
