Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
16.1,
16.9,
18.0,
18.1,
20.2,
20.3,
20.6,
21.6,
and get 151.79999999999998.
Then we take that total and get the average differential score 151.79999999999998 ÷ 8 = 18.974999999999998
Lastly we lop off all numbers past the first decimal point and we get
