Then we use the 8 lowest differentials according to this USGA table:
We add the lowest 8 differentials together, which are
14.0,
18.7,
20.1,
20.3,
20.4,
21.2,
21.3,
21.4,
and get 157.4.
Then we take that total and get the average differential score 157.4 ÷ 8 = 19.675
Lastly we lop off all numbers past the first decimal point and we get
Then we take that total and get the average differential score 157.4 ÷ 8 = 19.675
Lastly we lop off all numbers past the first decimal point and we get
