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: +2.4, +7.5, 1.9, 2.7
Lowest League Differentials Added Together : +2.4 + +7.5 + 1.9 + 2.7 = +5.3 Divide by 4 = +1.33

Jeff Mackay's League Handicap Factor prior to this round was +1.3


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 16, 2026 Round Handicap: -1.3 x (133/113) + (72.8 - 72) = +1
