Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
22.9,
24.0,
24.7,
27.2,
27.5,
28.1,
29.1,
29.4,
and get 212.9.
Then we take that total and get the average differential score 212.9 ÷ 8 = 26.6125
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 212.9 ÷ 8 = 26.6125
Lastly we lop off all numbers past the first decimal point and we get
