Then we use the 3 lowest differentials according to this USGA table:
We add the lowest 3 differentials together, which are
24.2,
24.9,
26.3,
and get 75.39999999999999.
Then we take that total and get the average differential score 75.39999999999999 ÷ 3 = 25.13333333333333
Lastly we lop off all numbers past the first decimal point and we get
