Then we use the 7 lowest differentials according to this USGA table:
We add the lowest 7 differentials together, which are
14.3,
14.8,
15.1,
15.4,
15.7,
15.9,
16.0,
and get 107.2.
Then we take that total and get the average differential score 107.2 ÷ 7 = 15.314285714285715
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 107.2 ÷ 7 = 15.314285714285715
Lastly we lop off all numbers past the first decimal point and we get
