Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
16.9,
17.4,
18.0,
18.4,
20.8,
21.3,
22.2,
22.2,
and get 157.19999999999996.
Then we take that total and get the average differential score 157.19999999999996 ÷ 8 = 19.649999999999995
Lastly we lop off all numbers past the first decimal point and we get
