Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
4.6,
8.0,
11.1,
11.3,
13.1,
14.2,
15.0,
16.0,
and get 93.3.
Then we take that total and get the average differential score 93.3 ÷ 8 = 11.6625
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 93.3 ÷ 8 = 11.6625
Lastly we lop off all numbers past the first decimal point and we get
