[top] Update test count comparison

Previously, the test looked for an exact match on accmumulated count.
This would occassionally break because the triggered alert could
have been fatal.  Fatal alerts continuously send alerts and thus
can cause the count to be bigger than expected.

Relax the check to be less than or equal.
