    Thank you VahidDM  for your prompt reply.

    Hi NewbieJono  ,

    Depending on the information you have provided, you can add a new measure:

    NEW Difference =
VAR _Totalswtiches =
    SELECTEDVALUE ( 'Table'[Total_switches] )
VAR _MOVEAVERAGE =
    MAXX (
        FILTER ( ALL ( 'Table' ), [Total_switches] < _Totalswtiches ),
        [NEW Average]
    )
RETURN
    IF ( _Totalswtiches = 0, 0, SUM ( 'Table'[NEW Average] ) - _MOVEAVERAGE )

     Final output:
