Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
7.0,
9.2,
9.9,
10.3,
10.9,
11.1,
11.8,
11.9,
and get 82.10000000000001.
Then we take that total and get the average differential score 82.10000000000001 ÷ 8 = 10.262500000000001
Lastly we lop off all numbers past the first decimal point and we get
Then we take that total and get the average differential score 82.10000000000001 ÷ 8 = 10.262500000000001
Lastly we lop off all numbers past the first decimal point and we get
