Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
11.3,
15.4,
16.3,
16.4,
17.4,
17.5,
17.8,
19.2,
and get 131.29999999999998.
Then we take that total and get the average differential score 131.29999999999998 ÷ 8 = 16.412499999999998
Lastly we lop off all numbers past the first decimal point and we get
