ICCF Rules (2023)
ICCF Rules from 1 December 2022
Errata: There is an error in the formulae in Appendix 1 of the 2023 rules (specifically, the formula for D2j). This will be corrected in the 2024 Rules, in the meantime the correct version of Appendix 1 can be downloaded from here. This should be used by any player wishing to reproduce the ratings calculations.
