| Date | Course | Tee | Slope | Rating | Score | Equation | Differential |
|---|---|---|---|---|---|---|---|
| Nov. 5, 2025 | Sleepy Hole Golf Course | Yellow | 119 | 67.3 | 86 | (86 - 67.3) x 113 ÷ 119 = | 17.8 |
| Sept. 3, 2025 | Cypress Creek Golfers' Club | Gold | 119 | 66.3 | 86 | (86 - 66.3) x 113 ÷ 119 = | 18.7 |
| Aug. 27, 2025 | Stumpy Lake Golf Course | Green | 108 | 65.6 | 81 | (81 - 65.6) x 113 ÷ 108 = | 16.1 |
| June 4, 2025 | Cypress Creek Golfers' Club | Gold | 119 | 66.3 | 82 | (82 - 66.3) x 113 ÷ 119 = | 14.9 |
| April 16, 2025 | Battlefield Golf Club | Gold | 116 | 65.6 | 81 | (81 - 65.6) x 113 ÷ 116 = | 15.0 |
| April 2, 2025 | Sleepy Hole Golf Course | Yellow | 119 | 67.3 | 84 | (84 - 67.3) x 113 ÷ 119 = | 15.9 |
Then we use the 2 lowest differentials according to this USGA table:
We add the lowest 2 differentials together, which are
14.9,
15.0,
and get 29.9.
Then we take that total and get the average differential score 29.9 ÷ 2 = 14.95
Lastly we lop off all numbers past the first decimal point and we get
Then we take that total and get the average differential score 29.9 ÷ 2 = 14.95
Lastly we lop off all numbers past the first decimal point and we get
