Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
7.8,
9.2,
9.4,
10.9,
13.0,
13.2,
13.5,
15.9,
and get 92.9.
Then we take that total and get the average differential score 92.9 ÷ 8 = 11.6125
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 92.9 ÷ 8 = 11.6125
Lastly we lop off all numbers past the first decimal point and we get
