Hi Ryan,
I would use COUNTIF for this task.
Row 19 is a Footer, therefore I can select the complete column as input.
Formula for cell B19= COUNTIF(B,"<1050")÷17
It will count every entry that is < 1050 and divide this result by 17.

Optional you can do it like this, then it will count all row that have an entry (>1).
Maybe one of your drivers is on vacation and should not be counted in this week.

Based on your region the , or the ; will be used to separate the different sections of a formula. If you write one thousand as 1,000.00 then the , is used as your formula separator. If you write one thousand as 1.000,00 then the ; is used as your formula separator.
Hope this will solve your question, please let me know if this worked for you or if something in unclear.
Regards Ralf
