Then we use the 2 lowest differentials according to this USGA table:
We add the lowest 2 differentials together, which are
11.9,
17.8,
and get 29.700000000000003.
Then we take that total and get the average differential score 29.700000000000003 ÷ 2 = 14.850000000000001
Lastly we lop off all numbers past the first decimal point and we get
