Need Help Running Index that Resets

Running Index that Resets based on criteria 

Hello i need help with this

 

I have a Table with many variables, that have Values, this value are evaluated as Status 1 or 0

where 0 = Ok, and 1 is Out of Specification

 

This variables also have a Criteria for Anomaly Analysis

 

So i have to make a colum that Count consecutive Status Events that are out of specification

When the counter number reach the same value as the criteria, then it has to show a value 1 in Anomaly Analysis

Like this?

 

let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Grouped Rows" = Table.Group(Source, {" VARIABLE"}, {{"Details", each _, type table [MONTH=nullable text, DAY=nullable number, HOUR=nullable number, #" VARIABLE"=nullable text, VALUE=nullable number, STATUS=nullable number, CRITERIA=nullable number]}}),
Custom1 = Table.TransformColumns(#"Grouped Rows", {{"Details", each Table.AddIndexColumn(_, "Index", 1,1)}}),
#"Expanded Details" = Table.ExpandTableColumn(Custom1, "Details", {"MONTH", "DAY", "HOUR", " VARIABLE", "VALUE", "STATUS", "CRITERIA", "Index"}, {"MONTH", "DAY", "HOUR", " VARIABLE.1", "VALUE", "STATUS", "CRITERIA", "Index"})
in
#"Expanded Details"

Hello, thanks for the help, i think we aproach to the objetive but still i need to make the counter reset every time the consecutive Status change, 

Actually the counter is reseting when the Variable change, but it should also resets when the Status change, i attach an image of the Counter-ToBe

I wast no very clear in this case, the column COUNTER, is the one that i dont know how to make,

If the Status is 1, The COUNTER has to increase from 1 until appear a row with Status 0, then it has to reset the counter, and start from 1 again.

In the formula bar, type:

 

= Table.AddColumn(SourceOrTableName, "ANOMALY ANALYSIS", each if [VALUE STATUS] = [CRITERIA STATUS] then 1 else null, type number)
