Calculation Enigma

I compute this year's daily goals based on last year/same month.  I get previous year like this- 364 days previous is the same weekday so it aligns properly.  

PYGA1=CALCULATE( 'Subscriber Activity'[Gross Adds],DATEADD('Calendar'[Calendar Date],-364,DAY)))

 Works great except then end of the month numbers are higher than they should be because it's calculating last year's first of the month on the last day of the month.  To correct it I did this: 

PYGA1 = IF('Calendar'[EndofMOnth]=DAY(SELECTEDVALUE('Calendar'[Calendar Date])),CALCULATE( 'Subscriber Activity'[Gross Adds],DATEADD('Calendar'[Calendar Date],-371,DAY)),CALCULATE( 'Subscriber Activity'[Gross Adds],DATEADD('Calendar'[Calendar Date],-364,DAY)))

It adjusts the last day of the month, but the total adds up to the same as it did when there was just the -364 measure.  So the PYALLGAs1 is showing the same total as it did in the first measure so it doesn't adjust each day higher like it should.  The goal for each day stays the same.  Not sure how this is even possible?  Any help greatly appreciated  

PYALLGAs1 = CALCULATE([PYGA1],

ALL('MyCalendar'[Date]))

GAGOAL = [PYGA1]/[PYALLGAs1]*[LocQuota1]

 So the essential problem is that the sum 15,457 is not correct.  If i export this and add it up it comes to 15,227.
