Getting a thread going for this. Short post for now, probably more when I have time. Here's an update with some stuff I was tinkering with (all on the talents/tables page). It's not dressed up yet, just some new numbers, and in general I have to decide how to present everything.
These are the two things TC wasn't that great at analyzing:
1) Effect of changes in total mana pool on longevity.
2) Correlation between mana consumption and added healing.
Slourette had done some interesting math on (2) a little ways back in the Resto thread. He uploaded a version of the sheet with a whole added framework for total healing done over a fight of fixed length. I liked where it was going, but I was hoping not to have to add a bunch of new machinery to the sheet. I think what I have here works pretty well. Briefly, it varies the % spell usage of Nourish vs. Rejuv to see the effect on mana consumption and on HPS. From that it computes the HPS gain from added MP5, assuming you vary spell usage to hold mana consumption constant. I added another column next to the scaling factors for stats, for now, to show what happens if you take this into account. They're pretty similar to the "sustained healing" stat weights people have been throwing around.
For (1), I just compute the MP5 equivalence of increases in starting mana pool, based on the current time to OOM. Those values are currently added to the MP5 scaling factors for Int/Furor/HotW/etc.
I think this all pretty good, but I want to find a way to nicely present everything without adding more clutter to the page.
EDIT: Main version of the sheet always lives on the main guide here:
