Variable percentiles for different groups

Hi Anonymous ,

To unpivot the table like this. Then you can get the excepted result by the transformed table.

M code for your reference.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("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", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Groupings = _t, Var_1 = _t, Var_2 = _t, Var_3 = _t, Var_4 = _t, Var_5 = _t, Var_6 = _t, Var_7 = _t]),
