Ok. It's better for the longer metric if they stay together.

I guess what matters is that it gives reasonable results on the current
metrics. I assume it does?
How much deduping is happening if you run all metrics?
For toplev on my long term todo list was to compare it against
a hopefully better schedule generated by or-tools, but I never
got around to coding that up.
