Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
4.6,
7.2,
7.6,
8.9,
9.2,
10.8,
11.2,
11.3,
and get 70.8.
Then we take that total and get the average differential score 70.8 ÷ 8 = 8.85
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 70.8 ÷ 8 = 8.85
Lastly we lop off all numbers past the first decimal point and we get
