    If I understand your question correctly, you can

    1. Add an Index column to your table, so as to be able to define the row
    2. Using List.Accumulate, add a custom column with this formula (which counts the number of nulls and/or blanks and then computes the percentage of columns that are non-blank):

     

    =1-
List.Accumulate({"Name","Description","Alias","Project required"},
                 0, 
                 (state, current)=>
                     if Record.Field(#"Added Index"{[Index]},current) = "" 
                        or Record.Field(#"Added Index"{[Index]},current) = null 
                        then state+1 else state)
     /4

=Table.AddColumn(PreviousStepName,"Test",each List.Sum(List.Transform({"Name","Description","Alias","Project required"},(x)=>Byte.From(Record.FieldOrDefault(_,x,null)<>null)))/4)
