About Player Rating Average Calculator

The average is the arithmetic mean of the match ratings, and the consistency index penalises the standard deviation relative to the rating scale. Two players can average the same rating while one is reliably solid and the other alternates between brilliant and anonymous, which the spread reveals.

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
