Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
18.3,
21.8,
22.0,
22.5,
24.4,
26.1,
27.8,
28.3,
and get 191.20000000000002.
Then we take that total and get the average differential score 191.20000000000002 ÷ 8 = 23.900000000000002
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 191.20000000000002 ÷ 8 = 23.900000000000002
Lastly we lop off all numbers past the first decimal point and we get
