WORLD HANDICAP SYSTEM
ESR - Exceptional Score Reduction

ESR is a procedure for dealing with exceptional scores which may indicate the player’s true ability. All scores are considered, rather than only tournament scores. 

How does it work?
  1. Calculate Score Differential once a score is posted and playing conditions calculation is applied (when appropriate). 
    • (Score differential is the adjusted gross score – course rating – playing conditions calculation) x (113/slope rating)
    • Don’t panic this calculation is done automatically by the computer and has been done this way for quite some time 
  2. If Score Differential is -7.0 to 9.9 strokes or better than the Handicap Index from when the round was played then ESR is -1
  3. If the Score Differential is -10 or better than the Handicap Index from when the round was played then the ESR is -2 
  4. Apply ESR table reduction to newly calculated Handicap.
        5. 
    • A reduction can be applied based on a single exceptional score.
    • Reductions for multiple exceptional scores are applied cumulatively.
    • A reduction is automatically applied within the calculation of a player’s updated Handicap Index following the submission of an exceptional score.
    • A reduction for an exceptional score is applied by adjusting each of the most recent 20 Score Differentials recorded in the player’s scoring record, which includes the exceptional score. As a result, the impact of the reduction will remain after the next score is submitted but will dilute over time as new scores are submitted.
    • Where there are fewer than 20 Score Differentials in a player’s scoring record at the time an exceptional score is submitted, the reduction is applied by adjusting all of the Score Differentials recorded in the player's scoring record, which includes the exceptional score.
