We might consider this, but this should be a rare event; or maybe it becomes
more common for certain types of simulations(?). Are you seeing this a lot?
Is there something unusual about the types of systems you are simulating?
Does this happen at the very beginning of your equilibration, or at later
times?

I'm not sure I understand your request. There is no (obvious) "right number"
of steps when you continue, as far as I can see.
