Convert Calculated Table to measure

Hi,

I've created a calculated table based on another calculated table as a temp solution as i wasn't able to create a measure to get the expected output. I am wondering, if this could be rather converted to a measure

I have a calculated table "CountrsPerDay" which has data grouped by day, countyId, SubCategoryId, categoryId, user, facilityId like below

i created 2 more calculated tables using the data above with the following dax to get status for each facility and another calculated table to get status for each county (below) 

SummaryByGS

VAR CombinedTable = ADDCOLUMNS(CountsPerDay, "PCsCount", RELATED('PCData'[PCCount]))

RETURN

ADDCOLUMNS(
        CALCULATETABLE(
                            SUMMARIZE(
                                        CombinedTable,
                                                CountsPerDay[date],
                                                CountsPerDay[countyId],
                                    
                                                "TotalPCCount",MIN('PCData'[PCCount]),
                                                "TotalUsers", CALCULATE(COUNT(CountsPerDay[TUser]), FILTER(CountsPerDay, CountsPerDay[CategoryId] = 2))
                                    ),
                                    FILTER(CategoryCountsPerDay, CountsPerDay[CategoryId] = 2)

                                ) ,
                   "PercentUse", DIVIDE([TotalUsers],[TotalPCCount])*100.0,              //Validation
                  "UseStatus", SWITCH(
                                            TRUE(),
                                            DIVIDE([TotalHosts],[TotalPCCount])*100.0 <= 1 || [TotalPCCount] <=5, "None",
                                            DIVIDE([TotalHosts],[TotalPCCount])*100.0 <= 30, "Minimal",
                                            DIVIDE([TotalHosts],[TotalPCCount])*100.0 > 30, "Regular"
                  )
)    

PCData Table is related via County Id, It has PCCounts by CountyId

The final result is displayed in tables and bar stack visuals showing different status and percentage values;

filters used - CountyId, FacilityId, Date (one day or range of dates)

This is a large dataset with 4+Millions rows and growing.. So, i would appreciate, if any1 here could help me convert these calculated tables to a measure
