The Club Ledger · No. 4

A game without a blunder is the exception.

For the typical player in the corpus, 20.4% of their games contain no blunder at all, about one in five, with the middle half of players between 16.2% and 25.1%. Measured across 466,424 analysed games from 247 players.

The figure is the median PLAYER's rate, not the corpus average: one prolific account holding a sixth of the games would otherwise be reported as though it were everybody. Playing a clean game is not the standard an amateur is failing to meet; it happens about one game in five.

Across 466,424 analysed games from 247 players.

The Club Ledger runs again tomorrow.
