Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
14.0,
15.4,
17.4,
17.5,
17.6,
17.8,
19.2,
21.4,
and get 140.3.
Then we take that total and get the average differential score 140.3 ÷ 8 = 17.5375
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 140.3 ÷ 8 = 17.5375
Lastly we lop off all numbers past the first decimal point and we get
