Then we use the 3 lowest differentials according to this USGA table:
We add the lowest 3 differentials together, which are
10.4,
11.1,
11.9,
and get 33.4.
Then we take that total and get the average differential score 33.4 ÷ 3 = 11.133333333333333
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 33.4 ÷ 3 = 11.133333333333333
