The good news for American golfers is that the WHS will look and feel much like the current USGA system. The WHS formula will be average-based, pulling from a golfer’s last 20 rounds (though all you need are three to establish a handicap) to calculate an index based on your best eight scores. (The current USGA system takes 10.) The new formula, which will count both nine- and 18-hole scores, will use a course’s Slope and Rating and will continue to produce an Index based off a players’ potential that’s then translated to a “playing handicap” for each set of tees at each course. One difference: These playing handicaps will represent the number of strokes a golfer gets in relation to par, rather than Course Rating, which will make it easier to run competitions where player use multiple tees (such as mixed tournaments).
