How these comparisons are calculated
Chess67 calculations from the Sep 2026 monthly rating update, using the same population as the USCF statistics pages: US members classified as active in the published monthly records, excluding lifetime-coded records, provisional ratings included. Ties share a rank; “lower” is strictly lower; national and state groups overlap. The target explorer keeps the population fixed, with this player at their recorded rating: it is a rating comparison, not a prediction of future rank.
