Desperately need help! Avg tickets for each hour for selected days of week in a selected date range

I have been trying every possible option for days now and I am just going around in circles.  I have a Date table, a Time table, and a data table. My data table contains one ticket per row with a timestamp.   I have broken out the time stamp into date, time, weekday and hour.  I have a day of week slicer that is connected to my date table ('Date'[Day of Week]) and a date slicer that is connected to my date table ('Date[MMYY]).
These are the measures that I am using: 
Total Tickets Countrows('Mytable')
Avg Per Day
AVERAGEX(DISTINCT('MyTable'[Date Created]),Calculate(Countrows('MyTable')/[Count Days]))

Count Days = DISTINCTCOUNT('MyTable'[Date Created])
Hourly Average = AVERAGEX(SUMMARIZE('MyTable', 'MyTable'[Hour],"Hourly Total",COUNTROWS('MyTable')),[Hourly Total])
 
The Hourly Average is where I am struggling.  The hourly average measure is actually giving me the totals per hour for the selected day where I need the hourly AVERAGE of tickets per hour of each day (for the slicer selected day(s) and Month(s).  
 
I tried Hourly Average = AVERAGEX(SUMMARIZE('MyTable', 'MyTable'[Hour],"Hourly Total",COUNTROWS('MyTable')),[Hourly Total])/[Count of Days] and that gives incorrect averages that do not add up. 
 
As a test, I tried manually adding in the count of days. and this works.  The averages per hour across the days is correct.   So All Saturday and Sundays in Jan, Feb, and March = 25. 
Hourly Average = AVERAGEX(SUMMARIZE('MyTable', 'MyTable'[Hour],"Hourly Total",COUNTROWS('MyTable')),[Hourly Total])/25. 
 
Here's what I get in excel and what I am expecting to see - Expected averages.JPG

How do I get this measure to work using the slicer selected days?

I finally got this to work!  Posting the solution here in case others have this issue.  At least this appears to function as expected. 

 

I changed the Count Days measure to be: 

Count of Days=CALCULATE(DISTINCTCOUNT('Date Created'[Date]),all('Date Created'[Date]))
 
Then my Per hour measure worked: 
AVERAGEX(SUMMARIZE('MyTable', 'MyTable'[Hour],"Hourly Total",COUNTROWS('MyTable')),[Hourly Total])/[Count of Days]

Hi @bevawn 

Please try

Hourly Average =
AVERAGEX (
    SUMMARIZE ( 'MyTable', 'MyTable'[Date Created], 'MyTable'[Hour] ),
    CALCULATE ( COUNTROWS ( 'MyTable' ) )
)
