Delete Rows If Column Has Fewer Than X Matches To Part String Match

I have data sets on multiple worksheets within a workbook (over 70). Based on the begining of a string, I need to count all instances with that begining, and if there are fewer than 12 instances, delete the entire row.

Data set example:

In this example, I need to count each instance of rows starting with 1/* - 9/*, and delete rows as mentioned. In other data sets the string might start Gi1/*, and so on. In the following code, if I do not loop, and only test against 1 value type, and ONLY run it once, it works. As soone as I try to loop through all possibilities, or run the macro a second time, it blanks out the entire worksheet, starting at row 3.

Dim c As Long
c = Worksheets(i).Range("A" & Rows.Count).End(xlUp).Row
With Range("A3:A" & c)
If Application.WorksheetFunction.CountIf(Worksheets(i).Columns(1), "1/*") < 12 Then
. AutoFilter field:=1, Criteria1:="1/*"
.Offset(1).Resize(.Rows.Count - 1, 1).EntireRow.Delete
.AutoFilter

I have also tried to concatenate a variable with my CountIf criteria, but that fails miserably.
