So was there enough countable slowness earlier in the run that you could
have predicted these runs would be slower overall?

My experience looking at Tempest run data is there can be as much as an
+60% variance from fastest and slowest nodes (same instance type) within
the same cloud provider, which is the reason we've never tried to
performance gate on it.

However if there was some earlier benchmark that would let you realize
that the whole run was slow, so give it more of a buffer, that would
probably be useful.
