Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
19.8,
20.6,
22.2,
22.8,
22.8,
23.1,
23.4,
23.4,
and get 178.10000000000002.
Then we take that total and get the average differential score 178.10000000000002 ÷ 8 = 22.262500000000003
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 178.10000000000002 ÷ 8 = 22.262500000000003
Lastly we lop off all numbers past the first decimal point and we get
