Some time ago the rules for TL-Champion tier promotion have changed. Instead of (the best) 200 games, now 500 games were used to compute the average. At that moment in time I had already played well over 200 games as TL, so I expected the average to stabilize after 300 games. I have played 350 games in 2019, but the average still goes up and down.
Has the game counter been reset to zero??
Please check it.
By the way, by changing the rules, good games (in the 200-500 best range) played before the rule change, have no effect. Being a numbers nerd, I have all my games on record, and the best 500 would give me 63.27 as WGT calculated 64.64.
