Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
14.8,
16.8,
18.1,
18.4,
20.3,
20.4,
20.6,
21.6,
and get 150.99999999999997.
Then we take that total and get the average differential score 150.99999999999997 ÷ 8 = 18.874999999999996
Lastly we lop off all numbers past the first decimal point and we get
