Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
13.0,
17.4,
19.1,
19.3,
20.1,
20.6,
21.4,
21.4,
and get 152.3.
Then we take that total and get the average differential score 152.3 ÷ 8 = 19.0375
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 152.3 ÷ 8 = 19.0375
