Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
12.9,
14.0,
16.3,
16.9,
17.0,
17.5,
17.9,
18.0,
and get 130.5.
Then we take that total and get the average differential score 130.5 ÷ 8 = 16.3125
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 130.5 ÷ 8 = 16.3125
Lastly we lop off all numbers past the first decimal point and we get
