Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
24.2,
26.1,
26.2,
27.1,
27.8,
27.9,
28.1,
28.2,
and get 215.6.
Then we take that total and get the average differential score 215.6 ÷ 8 = 26.95
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 215.6 ÷ 8 = 26.95
Lastly we lop off all numbers past the first decimal point and we get
