Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
14.2,
14.3,
14.8,
15.9,
16.0,
17.3,
18.0,
18.1,
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
