P(win) = 1 / (1 + 10^((rating_opp − rating_me)/400)). After a bout winner_points += N, loser_points += N/2 (FIE schedule).

Frequently Asked Questions

Where does the 400 come from?
It is the ELO scale constant: a 400-point advantage means the favourite is expected to win 10 times as often as the underdog.
Does this apply to all weapons?
The logistic model is weapon-agnostic, but FIE uses different rating pools for foil, epee and sabre — compare ratings from the same pool.
