Then we use the 2 lowest differentials according to this USGA table:
We add the lowest 2 differentials together, which are
5.7,
19.5,
and get 25.2.
Then we take that total and get the average differential score 25.2 ÷ 2 = 12.6
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 25.2 ÷ 2 = 12.6
Lastly we lop off all numbers past the first decimal point and we get
