Average of Averages

[Panto]

Hi everyone,

I'm struggling to handle an easy formula which is a nested average computed along a table with 2 dimension (AUTORE,LINK).

Basically I need to compute first of all an average for each author (AUTORE), and then use those aggregated values to create a second level average.

AUTORE LINK VALORE
autore_1 url_A 20
autore_1 url_B 20
autore_1 url_C 20
autore_1 url_D 20
autore_1 url_E 10
autore_1 url_F 10
autore_2 url_G 20
autore_3 url_H 5

For those familiar with Tableau, you could get the correct result with a nested Level of Deatil

I've already checked a similar post (https://community.powerbi.com/t5/Desktop/Average-of-average/m-p/1017894#M481085) but I'm not sure I'm understanding 100%, especially in my case where I have 2 dimension columns and one of them (LINK) is not involved in that caluclus.

Can anyone help?

Thanks in advance.

The general pattern is:

Measure = 

  AVERAGEX(

    SUMMARIZE(

      'Table',

      [Group],

      "__Average",AVERAGE('Table'[Column])

    ),

    [__Average]

  )
