Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
14.1,
16.0,
16.0,
16.9,
17.3,
17.8,
18.0,
18.6,
and get 134.7.
Then we take that total and get the average differential score 134.7 ÷ 8 = 16.8375
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 134.7 ÷ 8 = 16.8375
Lastly we lop off all numbers past the first decimal point and we get
