Then we use the 2 lowest differentials according to this USGA table:
We add the lowest 2 differentials together, which are
10.4,
11.9,
and get 22.3.
Then we take that total and get the average differential score 22.3 ÷ 2 = 11.15
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 22.3 ÷ 2 = 11.15
Lastly we lop off all numbers past the first decimal point and we get
