Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
7.6,
9.2,
10.2,
11.3,
11.5,
12.1,
13.0,
13.5,
and get 88.4.
Then we take that total and get the average differential score 88.4 ÷ 8 = 11.05
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 88.4 ÷ 8 = 11.05
Lastly we lop off all numbers past the first decimal point and we get
