Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
23.5,
23.7,
24.6,
25.2,
27.2,
28.3,
29.1,
29.1,
and get 210.70000000000002.
Then we take that total and get the average differential score 210.70000000000002 ÷ 8 = 26.337500000000002
Lastly we lop off all numbers past the first decimal point and we get
