@zhekov OK. My reasoning was that if you don't switch right away, it suggests empty INs could happen in situations where switching to a timeout source is not a good idea or the thing to do; so that maybe they could happen rarely and not be a real problem hence not being worth switching.
But if you tell me the reason to wait for 200 empty INs before switching is e.g. not to bother switching for short-lived output, I get that and then it wouldn't we worth worrying about decrementing the value.
