Calculate the average of Last 5 based on another column

[sfernamer]

Hi everyone!

I'm working with basketball data (basketball games) and I calculated the points scored by a player for the last game and the average excluding that game with measures. When new data is added, the calculation is refreshed, calculating again the values to be updated. 

I would like to do the same but not for the last game, I would like to take the last 5 games and do the same calculation (that should be recalculated when entering new data). The logic should be the same (using Date column) to the calculations below (to interact with filters correctly). I tried with TopN in a measure changing the order but not working.

Add a link with a pbix file where you can find the dataset and the measures already calculated (I can't add the pbix directly yet) : https://drive.google.com/drive/folders/1unoNI2WMIM3Jta-Q9DzbOg3Ie1gTtECc 

Could you give me advice, please? Thx in advance.

The calculations made (and working for the last game and all except last game):

Pts/G_Last =

VAR _date = CALCULATE( MAX(Hoja1[Date]), ALLSELECTED(Hoja1))

RETURN CALCULATE( [PtsScored/G], Hoja1[Date] = _date )

Pts/G_Avg =

VAR AvgGames = CALCULATE( MAX(Hoja1[Date]), ALLSELECTED(Hoja1))

RETURN CALCULATE( [PtsScored/G], Hoja1[Date] <> AvgGames)

Hi @Anonymous 

Thank you for your reply. I tested it on my pbix and, after editing a bit the formula, it worked. The final formula is the following one (I add the Date and Competition because I'm interested in recalculating depending on competition).

Last 10 Days =

VAR thisdate =

    MAX ( Hoja1[Date] )

VAR last10days =

    TOPN ( 10, FILTER ( ALLSELECTED( Hoja1[Date], Hoja1[Competition] ), Hoja1[Date] <= thisdate ), Hoja1[Date], DESC )

RETURN

    CALCULATE([PtsScored/G], last10days)

HI @sfernamer,

Perhaps you can take a look at the following link about similar requirement if its formula work on your report:
