Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
17.8,
18.1,
18.5,
18.5,
19.2,
19.3,
19.4,
19.9,
and get 150.70000000000002.
Then we take that total and get the average differential score 150.70000000000002 ÷ 8 = 18.837500000000002
Lastly we lop off all numbers past the first decimal point and we get
