Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
13.1,
14.9,
15.0,
15.5,
16.2,
16.9,
17.3,
17.7,
and get 126.6.
Then we take that total and get the average differential score 126.6 ÷ 8 = 15.825
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 126.6 ÷ 8 = 15.825
Lastly we lop off all numbers past the first decimal point and we get
