Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
8.9,
10.0,
16.9,
17.0,
17.4,
17.9,
18.2,
18.4,
and get 124.69999999999999.
Then we take that total and get the average differential score 124.69999999999999 ÷ 8 = 15.587499999999999
Lastly we lop off all numbers past the first decimal point and we get
