Time, List minus First, DAX Help

Hello Community, 

I'm trying to crack the code on DAX to subtract a previous from a next. 

In my example, using the data in the image, I need to subtract the 'Latest Time' from 'Run ID' 1 from the 'Earliest Time' from 'Run ID' 2. (This example would be 7:32AM - 7:29AM.) 

 

Any help with this would be appreciated!!

Hi @wayersGM 

Try this measure:

Measure = 
VAR _Start =
    MAX ( 'Table'[Earliest Time HrMin] )
VAR _End_Last =
    CALCULATE (
        MAX ( 'Table'[Latest Time] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Run ID] = MAX ( 'Table'[Run ID] ) - 1 )
    )
RETURN
    IF ( MAX ( 'Table'[Run ID] ) - 1 = 0, BLANK (), _End_Last - _Start )


Output:
