Based on a data set I have I'm looking to calculate a weighted average for each team based on Period (ie. Team A's score up until 08:00 only).

Can this be done using a Sumproduct or is there a different/easier way to do this?

Excel Facts

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.
If the Period will always be the same day as in your example:

Solution
this is not using the sumproduct.
And, this also only averages the items that are selected in the filter.

This works perfectly, thank you!
