Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
14.8,
18.1,
18.9,
19.5,
20.4,
20.8,
21.2,
21.4,
and get 155.10000000000002.
Then we take that total and get the average differential score 155.10000000000002 ÷ 8 = 19.387500000000003
Lastly we lop off all numbers past the first decimal point and we get
