Then we use the 1 lowest differentials according to this USGA table:
We add the lowest 1 differentials together, which are
11.9,
and get 11.9.
Then we take that total and get the average differential score 11.9 ÷ 1 = 11.9
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 11.9 ÷ 1 = 11.9
Lastly we lop off all numbers past the first decimal point and we get
