Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
18.0,
18.1,
19.9,
20.3,
21.0,
21.3,
22.7,
23.4,
and get 164.7.
Then we take that total and get the average differential score 164.7 ÷ 8 = 20.5875
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 164.7 ÷ 8 = 20.5875
Lastly we lop off all numbers past the first decimal point and we get
