Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
19.1,
22.4,
24.4,
25.7,
25.9,
26.6,
28.7,
29.1,
and get 201.89999999999998.
Then we take that total and get the average differential score 201.89999999999998 ÷ 8 = 25.237499999999997
Lastly we lop off all numbers past the first decimal point and we get
