Weighted average shows incorrect sum

Hi everyone,

so I managed to get total working now after finding this piece and added into my measure:

_WAVG = 
    
    VAR _Tot_Comments = CALCULATE(sum(JE_Q[Quantity]),ALLEXCEPT(JE_Q,JE_Q[Quantity]))

    VAR _Comments = SUM(JE_Q[Q_Quantity])

    VAR _Weight_Per = DIVIDE(_Comments,_Tot_Comments)

    VAR _Single = MIN(JE_Q[Time_Spent])

    VAR _WA = SUMX(JE_Q,_Single*[_WAVG_Weight])

    VAR _zTable =    
        ADDCOLUMNS(
        SUMMARIZE(
            JE_Q,
            JE_Q[Time_Spent]),
        "x",_WA
        )

    RETURN

    IF(HASONEVALUE(JE_Q[Time_Spent]),SUMX(VALUES(JE_Q[Time_Spent]),SUMX(_zTable,_Weight_Per * _Single)),    SUMX (
    VALUES ( JE_Q[Time_Spent]),
    CALCULATE (
        DIVIDE (
            SUM ( JE_Q[Quantity] ),
            CALCULATE (
                SUM ( JE_Q[Quantity] ),
               ALLSELECTED (JE_Q[Time_Spent])
            )
        )
            * AVERAGE ( JE_Q[Time_Spent])
    )
))
    

TBH, I do not get it why it is working, I just realized that in my previous formulas I used MIN() in calculation for total, which was wrong and returned 25, what was just count of all categories, but is there a better/cleaner way how to write this?

Thanks!
