Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
19.9,
20.3,
20.3,
21.0,
21.3,
22.2,
23.5,
23.7,
and get 172.2.
Then we take that total and get the average differential score 172.2 ÷ 8 = 21.525
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 172.2 ÷ 8 = 21.525
Lastly we lop off all numbers past the first decimal point and we get
