Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
4.6,
14.4,
19.3,
19.5,
19.7,
20.2,
22.1,
24.2,
and get 144.0.
Then we take that total and get the average differential score 144.0 ÷ 8 = 18.0
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 144.0 ÷ 8 = 18.0
Lastly we lop off all numbers past the first decimal point and we get
