Weekly Rolling average for already calculated measure

Below are the formulas for all the measures I'm using.  Without seeing what you're expected result based on the data provided, it's kind of difficult to figure out what, if anything, is wrong.  Could you please provide some details?

ALL Present:=CALCULATE(
	COUNTROWS(AttendanceOvertime),
	AttendanceOvertime[Statistical meaning] IN {"Present", "Approved Educational Activity"}
)


ALL Present Running Total:=CALCULATE(
		[ALL Present],
		FILTER(
			ALL('Calendar'),
			'Calendar'[Date] <= MAX('Calendar'[Date])
		)
	)


Measure:=CALCULATE (
	COUNT ( AttendanceOvertime[Statistical meaning] ),
	AttendanceOvertime[Statistical meaning] IN { "Attendance not required" }
)


Measure Running Total:=CALCULATE(
		[Measure],
		FILTER(
			ALL('Calendar'),
			'Calendar'[Date] <= MAX('Calendar'[Date])
		)
	)


All Present Running Average:=DIVIDE(
		[ALL Present Running Total],
		[Measure Running Total],
		BLANK()
	)
