Then we use the 5 lowest differentials according to this USGA table:
We add the lowest 5 differentials together, which are
23.5,
24.2,
24.9,
26.1,
26.3,
and get 124.99999999999999.
Then we take that total and get the average differential score 124.99999999999999 ÷ 5 = 24.999999999999996
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 124.99999999999999 ÷ 5 = 24.999999999999996
