关于此计算器

This calculator provides a preliminary calculation based on the standard ELO method for RCF rating changes. The official rating is finalised by the federation.

无RCF等级分的棋手

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

RCF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 below 2400, K=10 from 2400.
