Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
11.1,
14.3,
14.8,
15.0,
15.1,
15.4,
16.0,
16.0,
and get 117.7.
Then we take that total and get the average differential score 117.7 ÷ 8 = 14.7125
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 117.7 ÷ 8 = 14.7125
Lastly we lop off all numbers past the first decimal point and we get
