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: 1.9, 2.7, 3.6, 1.9
Lowest League Differentials Added Together : 1.9 + 2.7 + 3.6 + 1.9 = 10.1 Divide by 4 = 2.53

Jeff Mackay's League Handicap Factor prior to this round was 2.5


Handicap Calculation for this round: Factor x Slope/113 + (Rating of Tee Used - par of course) = League Handicap (Rounded to a Whole Number)
Jeff Mackay played Mickelson National - 18 Holes from the Deck II tees (Slope: 133 , Rating: 72.8)

Sep 2, 2026 Round Handicap: 2.5 x (133/113) + (72.8 - 72) = 4
