How Stableford points work
Stableford rewards each hole against par on your net score: the gross score minus the strokes you receive on that hole. On the standard table a net double bogey or worse scores 0, a bogey 1, a par 2, a birdie 3, an eagle 4 and an albatross 5. Total the points over the round and the highest total wins.
The modified table is more aggressive: an albatross is 8, an eagle 5, a birdie 2, a par 0, a bogey minus 1 and a double bogey or worse minus 3.
Why 36 matters
On the standard table a golfer who makes a net par on every hole scores 36 points over 18 holes. So 36 points is playing exactly to handicap, and 38 or 40 is a good day. This is also the idea behind quota formats, where the target is 36 minus your handicap.
Strokes by hole
Strokes go to the hardest holes first, by stroke index. A Playing Handicap of 12 gets one stroke on the holes with stroke index 1 to 12. The calculator reads your stroke indexes from the table above, so you can paste in the card for the course you are playing. If your Playing Handicap is above 18, you get a second stroke on the hardest holes again.
Pick-ups
Leave a hole blank if you picked up. A pick-up scores zero, the same as a net double bogey or worse, which is why Stableford speeds play: there is no benefit in grinding out an 8.
