Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
11.3,
16.3,
16.4,
17.5,
17.8,
19.2,
19.3,
19.7,
and get 137.5.
Then we take that total and get the average differential score 137.5 ÷ 8 = 17.1875
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 137.5 ÷ 8 = 17.1875
Lastly we lop off all numbers past the first decimal point and we get
