Count values in a matrix over a certain value

You could use a measure that counts the number of times the total is over 30 when iterating over the time component. 

Over 30 =
COUNTROWS(
    FILTER( VALUES( 'Date'[Time Value] ), [Some Total Measure] >= 30 )
)

If over both time and wings, then this:

Over 30 =
COUNTROWS(
    FILTER(
        SUMMARIZE( FactTable, 'Date'[Time Value], DimensionTable[Wings] ),
        [Some Total Measure] >= 30
    )
)

For more help though, we need some data to work with and an undestanding of your model. See below for links to show how to provide usable data. We cannot use images to get data from. Great for what your target is, but I cannot type all of that in.
