Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
20.3,
20.4,
20.5,
20.6,
21.3,
21.6,
22.2,
24.1,
and get 171.0.
Then we take that total and get the average differential score 171.0 ÷ 8 = 21.375
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 171.0 ÷ 8 = 21.375
Lastly we lop off all numbers past the first decimal point and we get
