Average per quarter

If you want the average of a number you’ve already calculated, try using SUMMARIZE to iterate through a virtual table based on those calculations.

For example,

AVERAGEX(
SUMMARIZE ( Dates, QuarterHourColumn,
“Average Results”, PalletsMeasures ),
[Average Results] )

This is the technique I would try first.
