No players had to change the tournament categories, but in one case it was very close! @sammy00 (migmag) had an average rating of 1499,5 and thus by a thread could keep tier 1!
Maybe I have missed something, but how @agreste with ELO 1836 stayed in the Tournament 2 (1500-1799)?
I did the math and averaged all his ratings (of course not bullet and not chess960)
1730 1795 1779 1788 1795 1789 1822 and 1836, outcome was 1791,75
I don't know exactly the rules, but I have no problem with being moved to tournament 3 if you feel it is necessary.
Next time you would start in that group, if your rating stays above 1800.
