Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
11.3,
15.7,
17.7,
17.8,
17.9,
19.7,
21.5,
21.5,
and get 143.10000000000002.
Then we take that total and get the average differential score 143.10000000000002 ÷ 8 = 17.887500000000003
Lastly we lop off all numbers past the first decimal point and we get
