Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
9.9,
14.1,
16.4,
17.0,
17.0,
17.8,
18.0,
18.4,
and get 128.6.
Then we take that total and get the average differential score 128.6 ÷ 8 = 16.075
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 128.6 ÷ 8 = 16.075
Lastly we lop off all numbers past the first decimal point and we get
