关于此计算器

This calculator provides an ELO-based preliminary calculation for ECF rating changes. The official ECF rating is finalised by the English Chess Federation.

无ECF等级分的棋手

For players without an ECF rating, the tool can show a starting performance. The official starting rating is subject to ECF rules.

ECF等级分如何运作

预期得分:

E = 1 / (1 + 10^((Rb - Ra) / 400))

新等级分:

R'a = Ra + K × (S - E)

Simplified coefficients: K=40 for fewer than 30 games, K=20 for established players.
