Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
4.6,
11.1,
14.5,
16.0,
16.3,
16.9,
17.0,
17.8,
and get 114.2.
Then we take that total and get the average differential score 114.2 ÷ 8 = 14.275
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 114.2 ÷ 8 = 14.275
Lastly we lop off all numbers past the first decimal point and we get
