    mgrayTCB try this:

     

    MS Months Chg2 =
AVERAGEX (
    FILTER (
        ADDCOLUMNS (
            Project,
            "@datechg",
                VAR SSdate =
                    CALCULATE ( MINX ( MilestoneSS, MilestoneSS[DateActOrEstSS] ) )
                VAR Curdate =
                    CALCULATE ( MAXX ( Milestones, Milestones[DateActOrEst] ) )
                VAR datechg =
                    DATEDIFF ( SSdate, Curdate, DAY ) / 30.4
                RETURN
                    datechg
        ),
        [@datechg] <> 0
    ),
    [@datechg]
)

    mgrayTCB no problem.

    Please also add calculate on top of minx and maxx in lines 7 and 9 and you can actually remove the calculate we added before, it has no meaning. All there is vars anyway.

    BTW, in general, you don't need the calculate in line 2.

I adjusted them both to use values(project[projectname]) and I still get different answers. The MS Delay Faster does produce the correct averge of the items above but I dont understand why MS Delay produces a different answer. It is always different even with different MS Short Names selected. It is always lower.

mgrayTCB can you test this scenario and put it also in the visual:

 

MS Months Chg2 Wrong =
AVERAGEX (
        ADDCOLUMNS (
            VALUES('Project'[ProjectName]),
            "@datechg",
                VAR SSdate =
                    CALCULATE ( MINX ( MilestoneSS, MilestoneSS[DateActOrEstSS] ) )
                VAR Curdate =
                    CALCULATE ( MAXX ( Milestones, Milestones[DateActOrEst] ) )
                VAR datechg =
                    DATEDIFF ( SSdate, Curdate, DAY ) / 30.4
                RETURN
                    datechg
    ),
    [@datechg]
)

    That seems to be averaging in zeros. You are no longer limiting the virtual table to datechg <> 0. Why is that not working in the version without the virtual column?

    mgrayTCB in ms delay can you also add calculate on top of the date diff 4 rows before the end of the code
