Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
17.8,
19.0,
19.5,
20.1,
20.2,
21.4,
21.4,
22.1,
and get 161.5.
Then we take that total and get the average differential score 161.5 ÷ 8 = 20.1875
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 161.5 ÷ 8 = 20.1875
Lastly we lop off all numbers past the first decimal point and we get
