sum of boxes with value (not total sum of values)

[apenaranda]

Hello,
What would be the dax formula so that it counts the total but not the sum of the row but the sum of the users who do have some data
Example:
On 12/30/2022 there are three users who have data, the total should be 3 (in this case it matches the sum but does not do it correctly)
On 12/29/2022 there are four users who have data, the total should be 4
like this with all the rows.

Thank you

@Syndicate_Admin , supongamos que su medida actual es M1

A continuación, cree una medida como

if(isinscope(Tabla[Usuario]), [M1] , countx(valores(Tabla[Usuario]), if(not(isblank([M1])) , [Usuario], blank() ) ) )

Well, it worked for me but I see that things are more difficult than I thought. The fact is that now I want to divide the rows by ADDing all the values and dividing it by the number of rows there are.
According to the screenshot I attached it would be:

= add values (63 if I counted correctly) / count rows (19)
Thank you.
