Then we use the 7 lowest differentials according to this USGA table:
We add the lowest 7 differentials together, which are
5.6,
8.8,
9.1,
10.2,
11.5,
11.9,
12.0,
and get 69.1.
Then we take that total and get the average differential score 69.1 ÷ 7 = 9.87142857142857
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 69.1 ÷ 7 = 9.87142857142857
Lastly we lop off all numbers past the first decimal point and we get
