According to wikipedia,
Grandmasters are among the top 0.02% of tournament players.
International Masters among the top 0.25% " ".
Experts among the top 1% " ".
This information however is irrelevant to me.
How do the other classes match up? I'm most curious about A (1800-2000) and B (1600-1800) classes (USCF or FIDE, it doesn't matter.)
Sources would be nice.
Thanks in advance.
Answer on B class chess players are among the top what per cent?
I couldn't find an exact answer.
I found a 'statistical distribution' of players and ratings from
the ECF system, that someone has taken the time to create.
From the graph, it follows the 'bell curve' form.
The distribution of grades pretty much fits into the normal distribution.
Quote from the comments:
The distribution is “left-handed” because of the existence of large sub-pool, that of juniors.
Most of these are rubbish and won’t improve and will eventually drop out of the list,
