Is there a limited time a for next loop will run? (not

This works fine for small amounts of data, but seems to
exit around 96 samples. If I then re-run it its fine and
exits correctly.

If you're deleting cells, better to iterate from bottom to top or right to left.
So don't use a For Each loop, use

Dim n As Long
':
For n = Range("Results").Rows.Count To 1 Step -1
':
