Strength over time

Daily results are combined into one point. Dashed stretches indicate a less stable estimate.

How it works

  • Strength is a numeric summary of how a fencer has performed against other fencers over time.
  • The estimate usually settles after about 12 bouts, so early data can move sharply.
  • New fencers begin around 2500, but with high uncertainty.
  • Pools, direct eliminations, and mixed-gender bouts are tracked separately.
  • The scale runs from roughly 0 to 5000, with the average around 2500.
  • Beating much stronger fencers moves the estimate more than beating weaker ones.
  • Win probability reflects rating differences only, not style matchups or familiarity.
  • Per-bout changes are available in bout history.
