Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
19.5,
20.1,
20.3,
21.0,
21.3,
21.4,
21.4,
21.8,
and get 166.8.
Then we take that total and get the average differential score 166.8 ÷ 8 = 20.85
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 166.8 ÷ 8 = 20.85
Lastly we lop off all numbers past the first decimal point and we get
