Then we use the 5 lowest differentials according to this USGA table:
We add the lowest 5 differentials together, which are
16.3,
19.0,
20.2,
21.4,
21.4,
and get 98.30000000000001.
Then we take that total and get the average differential score 98.30000000000001 ÷ 5 = 19.660000000000004
Lastly we lop off all numbers past the first decimal point and we get
