This is really useful info ! I've started moving my Tribe curations to match what you've got here, and can see the difference in terms of earnings. Previously I was using the LOLZ curator for all of them, so I've built up a decent amount of LOLZ, but using the direct curators for each token definitely produces higher reward values.
Doing the whole rebalancing thing will probably have to wait a month or two; January is normally crazy busy for me in the real world, so finding time is an issue !
