1% of Class A players - become Masters

As a player reaches 1800, he is statistically better than 80% or so of all rated adult chess players.

In order to hold a Class A rating, now the player is expected to score 25% vs. Experts (95th percentile).

Experts make very few mistakes compared to Class B and C players.

The Expert level is the third major rating plateau…and very few climb past it.

Most players have several master skins by the time they reach 2000, but in order to hold an expert rating, the player must now score 1 out of 4 against masters…no easy task!

To move from the 95th percentile of Expert to the 99th percentile of master is a huge step.

To hold a master rating, the player must score at least 75% against experts and break even with masters.

It is well documented that the toughest 100 rating points to attain are between 2100 and 2200.
Statistically, 5% of rated players reach the Expert (2000) level, and 1% achieve the Master (2200) level.

There are higher levels of Master (SM, IM, and GM), - less than 1% of all tournament players fall into this range.

'......I don't know much about stats or figures but this ELO rating racket seems like a numbers game to me......
