    I'm working with my assumption and came up with this...

     

    Weighted Average Product Time = 
    VAR AllProducts = 
        CALCULATETABLE(
            VALUES(Products[Product]),
            ALL(Products)
        )
    VAR	TotalProductCount =
	    CALCULATE(
		    [Product Count],
    		ALL(Products)
	    )
    RETURN 

    DIVIDE(
        SUMX(
            AllProducts,
            [Product Count] * [Total Product Time]
        ),
        TotalProductCount,
        BLANK()
    )

     

     

    Here's the results

    Hope this helps!  ğŸ™‚

    Anonymous one more question: how is the weighing calculated?  I'm assuming 

    (product total count) * (product time) / (total product count)

    Hi,

    Try these measures:

    Total time = SUM(Data[Time])
    Product count = COUNTROWS(Data)
    Measure 2 = SUMX(VALUES(Data[Product]),[Total time]*[Product count])/[Product count]
    Hope this helps.

      Ashish_Mathur  not only did I offer a solution five hours ago, someone else offered essentially the same solution three hours ago.  Your input was warranted?
