Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
22.4,
23.4,
24.4,
25.7,
25.9,
26.6,
29.2,
29.5,
and get 207.09999999999997.
Then we take that total and get the average differential score 207.09999999999997 ÷ 8 = 25.887499999999996
Lastly we lop off all numbers past the first decimal point and we get
