Filter visual table with a measure not dynamically updated

hi,

I'm using the visual table below with this measures.

AverageDays = 
var a=SUMX(ALLSELECTED('Table'),'Table'[Number of days])
var b=COUNTROWS(FILTER(ALLSELECTED('Table'),'Table'[Number of days]<>BLANK()))
return a/b

Measure = IF(MAX('Table'[Number of days])>'Table'[AverageDays],1,0)

I use "Measure" to filter my visual table to display values only greater than the average.

thanks to Anonymous for the solution but i have a question.

When i've filtered the visual, i get this :

Now, i want to let the users to be able to filter by type using slicer. I mean when they select 'Red', they should get this :

But in fact they get this because when they use the slicer 'type' the measure 'AverageDays' is automatically updated. So the AverageDays was 380 and is now 987 and it displays only values greater than this.

I've tried using 'modify interactions' for slicer to set 'none' for the measure 'AverageDays' but still not working.

How can i do so the measure isn't updated when using the slicers ?

Thanks a lot again !
