Then we use the 3 lowest differentials according to this USGA table:
We add the lowest 3 differentials together, which are
10.4,
11.4,
11.9,
and get 33.7.
Then we take that total and get the average differential score 33.7 ÷ 3 = 11.233333333333334
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 33.7 ÷ 3 = 11.233333333333334
