Then we use the 3 lowest differentials according to this USGA table:
We add the lowest 3 differentials together, which are
25.6,
26.2,
27.8,
and get 79.6.
Then we take that total and get the average differential score 79.6 ÷ 3 = 26.53333333333333
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 79.6 ÷ 3 = 26.53333333333333
Lastly we lop off all numbers past the first decimal point and we get
