Calculated table or column with a rolling average

Thanks for helping.  The calculation for the rolling average works perfect if I place it in visual as you suggest.  I want to put the average into a table so that I can do other things with it, mainly figure out how many times it is greater than a specified value.  I've been experimenting with something like below.

3daycount =
COUNTROWS (
    FILTER (
        SUMMARIZE (
            FactPumpageDaily,
            FactPumpageDaily[Date],
            FactPumpageDaily[WellCode],
            "3DAY",
                CALCULATE (
                    AVERAGEX ( FactPumpageDaily, FactPumpageDaily[RunHours] ),
                    DATESINPERIOD ( DimDates[Date], MAX ( DimDates[Date] ), -3, DAY )
                )
        ),
        [3DAY] >= 15
    )
)

The running average is the average of the hours from the selected date and the preceding two days.  It works as a measure just fine as defined below.  (My sample data just has enough info to check for 5/1/2021.)  Ultimately, I am trying to count the number of times the average is >= 15.   The Calculatetable in my question is just my first step in that process.   After getting the CalculateTable/summarize to work, my intent is to wrap it in a CountRows, somthing like below

3daycount =
COUNTROWS (
    FILTER (
        SUMMARIZE (
            FactPumpageDaily,
            FactPumpageDaily[Date],
            FactPumpageDaily[WellCode],
            "3DAY",
                CALCULATE (
                    AVERAGEX ( FactPumpageDaily, FactPumpageDaily[RunHours] ),
                    DATESINPERIOD ( DimDates[Date], MAX ( DimDates[Date] ), -3, DAY )
                )
        ),
        [3DAY] >= 15
    )
)

When I use this, I always just get the count for the record date (which is 1 or 0), even when I add an All(DimDates[Date]) to the calculate to change the date context.
