Don't have time to implement full solution but tried it with just
commenting out writing errors back to docs. So here is what it looks like
without jitter and without writing error back:

There is still a blip but scheduler utilization doesn't go above 20% even.
Bulk updates would be somewhere in between this and worst case above then. But
that is more involved to get correctly and is a bigger change. It would be a
separate PR anyway.
