Power Query how to get the date just before another date

Hello, 

 

I need to calculate the average value of the column "value" for the former sprint. I have added a column "date of end" which the date of end of each sprint. 

I have added a custom column that shows 1 when "asofdate" = "date of end" so that I know the average we had at the end of a sprint. But that way I can have a match also for past or future sprints. I need only to have a match for my former sprint that is over.

 

How can I calculate this average please?

The simplest way is fill up and group by the end date to get the average value.

Or just copy and paste the following code into advanced editor and then check the applied steps.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [asofdate = _t, url = _t, KPI_name = _t, Value = _t, #"Date of end" = _t, Custom = _t]),
