Lichess question

I downloaded several 2019 PGN's. They contain about 30 million games each. When I make a selection on elo=2200+ (both players) the output is below 1%. Makes me wonder, either there are not many strong players or they maintain a non-standard elo rating.

Ratings are not far from real world.
1% of 30 million games (by month) is 300 000 games (by month). Do you think that's "not many" ?

Hi Ed,

Are these engine games or human games? Human games I am not interested in... :) :) :o

Human games only, will extract comp games later and make them available.

I am around 2100 in lichess, that makes top 3.5%.

If you filters 2200+for both players, it can be 1% of games. (mutual filter).

Need to be careful with the filtering - after filtering out games that terminated abnormally and with ELO > 2450 I ended up with 30,192 games for the June database .. :D
