Switch and calculate

Hi, Anonymous 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

You may create a measure as below.

Percenatage = 
var _table = ALLSELECTED('Table')
var tab = 
SUMMARIZE(
    'Table',
    'Table'[Weekname],
    "Result",
    var _weekname = [Weekname]
    var newtab = 
    SUMMARIZE(
        _table,
        'Table'[Hour],
        'Table'[Weekname],
        'Table'[Location_name],
        "flag",
        IF(
            'Table'[Hour]>4&&[Location_name]<>"",
            1,0
        )
    )
    return
    DIVIDE(
        CALCULATE(
            DISTINCTCOUNT('Table'[Location_name]),
            FILTER(
                  newtab,
                  'Table'[Weekname]=_weekname&&
                  [flag]=1
            )
        ),
        COUNTROWS(
            FILTER(
                newtab,
                [Weekname]=_weekname&&
                [Location_name]<>""
            )
        )
    )
)
return
SUMX(
    tab,
    [Result]
)

The overall count for '20WK25' with a location is 10. The distinct count location name with criteria of hour>4 for '20WK25' is 5. Here is the result.

If I misunderstand your thoughts, please show us your expected result. 

Best Regards

Allan
