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: 0.2, +3.2, +0.7, 0.2
Lowest League Differentials Added Together : 0.2 + +3.2 + +0.7 + 0.2 = +3.5 Divide by 4 = +0.88

Jeff Mackay's League Handicap Factor prior to this round was +0.9


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)

Jun 3, 2026 Round Handicap: -0.9 x (133/113) + (72.8 - 72) = 0
