What I ifind interesting about this is that whereas I had been
concerned that adding hot standby late in the development cycle might
be destabilize the tree and add lots of time to the release cycle it
seems having it might actually increase our ability to see problems in

I think a function infering cost from time spent could be calculated
It sounds like you're proposing to compare the time spent planning to
the estimated execution time. AFAICS, those things are unrelated, so
I'm not sure what you hope to figure out by comparing them.
The idea is: If we are to spend a LOT of resources executing the
