Count columns that are not blank, null or zero based on column string condition

This would be my approach: 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WSsrMTlXSAVPFQNoQiCHIyMAASJqASQjbUClWJ1opObEIpBBKGUIxSN7CAKLMAJU2UIqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [product = _t, product_group = _t, #"USA mins" = _t, #"CAN mins" = _t, #"SWE mins" = _t, #"USA profit" = _t, #"CAN profits" = _t, #"SWE profits" = _t, #"USA (other metrics)" = _t]),
    #"Replaced Value" = Table.ReplaceValue(Source,null,"0",Replacer.ReplaceValue,{"product", "product_group", "USA mins", "CAN mins", "SWE mins", "USA profit", "CAN profits", "SWE profits", "USA (other metrics)"}),
    #"Replaced Value1" = Table.ReplaceValue(#"Replaced Value","","0",Replacer.ReplaceValue,{"product", "product_group", "USA mins", "CAN mins", "SWE mins", "USA profit", "CAN profits", "SWE profits", "USA (other metrics)"}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Replaced Value1", {"product", "product_group"}, "Attribute", "Value"),
    #"Added Custom" = Table.AddColumn(#"Unpivoted Other Columns", "Mins", each Text.Contains([Attribute], "mins")),
    #"Filtered Rows" = Table.SelectRows(#"Added Custom", each ([Mins] = true) and ([Value] = "1")),
    #"Grouped Rows" = Table.Group(#"Filtered Rows", {"product"}, {{"Count", each Table.RowCount(_), Int64.Type}}),
    #"Merged Queries" = Table.NestedJoin(Source, {"product"}, #"Grouped Rows", {"product"}, "Grouped Rows", JoinKind.LeftOuter),
    #"Expanded Grouped Rows" = Table.ExpandTableColumn(#"Merged Queries", "Grouped Rows", {"Count"}, {"Count"})
in
    #"Expanded Grouped Rows"
