Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
22.4,
25.6,
26.5,
26.5,
26.7,
27.8,
27.9,
28.3,
and get 211.70000000000002.
Then we take that total and get the average differential score 211.70000000000002 ÷ 8 = 26.462500000000002
Lastly we lop off all numbers past the first decimal point and we get
