Then we use the 5 lowest differentials according to this USGA table:
We add the lowest 5 differentials together, which are
5.7,
7.0,
7.3,
9.1,
9.7,
and get 38.8.
Then we take that total and get the average differential score 38.8 ÷ 5 = 7.76
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 38.8 ÷ 5 = 7.76
Lastly we lop off all numbers past the first decimal point and we get
