Then we use the 2 lowest differentials according to this USGA table:
We add the lowest 2 differentials together, which are
9.4,
13.0,
and get 22.4.
Then we take that total and get the average differential score 22.4 ÷ 2 = 11.2
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 22.4 ÷ 2 = 11.2
Lastly we lop off all numbers past the first decimal point and we get
