Count or Sum of Unique Key Column but Restart when Sequence Interrupted

[Anonymous]

This is my very first post, so please excuse any newbie mistakes.  I have been working on my issue for over a week and have tried many solutions, but none have worked.  I am building Control Charts and I am attempting to identify patterns in the date and I am trying to count occurences but need to restart the count when a unique key is interrupted.  See below.

I am trying to count the number of KEY rows in sequence, but need it to restart the count when a different key appears. I would like the formula to be a calculated column.  As you can see I have it summing ALL of the KEY as "SUMA" and EACh of the KEY as "SUMM".  You can see that the data is in numerial order using WkYearNum and always will be.  Any help is appreciated. If I need to post something else to help please let me know?

I forgot to mention. The numbers written in RED are the desired result. In some cases this will go up to 16. It just depends on data.  The total column is grouped by quarter.

Correction: It should read "patterns in the data"...NOT date.

Can you show your current formulas for SUMA and SumM?

Yes.  But I had to also add a few columns I left out so they make sense. See below.

SUMA = CALCULATE(
SUM( Control_Chart_Sample_Size_Temp[Valid_Zone_CL]),
FILTER( ALL(Control_Chart_Sample_Size_Temp) ,
SUMX( FILTER(Control_Chart_Sample_Size_Temp, EARLIER(Control_Chart_Sample_Size_Temp[KEY]) = Control_Chart_Sample_Size_Temp[KEY] ), Control_Chart_Sample_Size_Temp[Valid_Zone_CL])
)
)

SumM = VAR m = [Equalizer_Zone_CLB]
RETURN
CALCULATE ( SUM( Control_Chart_Sample_Size_Temp[Valid_Zone_CL] ), FILTER (Control_Chart_Sample_Size_Temp,m ) )

EQUALIZER_ZONE_CLB is a measure that tries to use the MAX of WkYearNum to create a new unique key, but this measure doesnt work either.
