We compared 19,000+ competitors to measure how much BJJ belts actually overlap.
The problem is look at top nogi purple belts in the system. They are slightly above average black belts according to the ELO.
If the system was well calibrated, there would not be a need to do a “promotion bonus” when people move up.
It’s a good system but under states how good top purple belts are. And probably over rates less competitive black belts.
Especially in nogi.
The K factor isn’t high enough for top guys to catch up.
This was a great read.
Interesting stuff Berimbozo! If you’re planning to do further analysis, I think belts vs perceived happiness would provide many key insights for us readers
Awesome! Always wondered about this.
