Then we use the 3 lowest differentials according to this USGA table:
We add the lowest 3 differentials together, which are
14.8,
18.4,
19.7,
and get 52.900000000000006.
Then we take that total and get the average differential score 52.900000000000006 ÷ 3 = 17.633333333333336
Lastly we lop off all numbers past the first decimal point and we get
