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.

Lowest League Differentials Added Together : 12.9 + 19.9 + 13.9 + 18.1 = 64.8 Divide by 4 = 16.20
