League Handicap Calculation * Differential for Each Round = (Gross Score - Course Rating) x (113 / Slope)

League handicaps are calculated using a player's 4 BEST league scores out of their last 7 league scores.
4 Lowest League Differentials: 19.9, 13.9, 18.1, 12.3
Lowest League Differentials Added Together : 19.9 + 13.9 + 18.1 + 12.3 = 64.2 Divide by 4 = 16.05

Derek Iwanicka's League Handicap Factor prior to this round was 16.1


Handicap Calculation for this round: Factor x Slope/113 + (Rating of Tee Used - par of course) = League Handicap (Rounded to a Whole Number)
Derek Iwanicka played Mickelson National - 18 Holes from the Deck III tees (Slope: 129 , Rating: 71.3)

Jun 24, 2026 Round Handicap: 16.1 x (129/113) + (71.3 - 72) = 18
