Since every difficulty has a *chance* for an additional DB (see the difficulty overview in my sig) I have trouble reading your equations, and they might in fact be very misleading if looked at without context. In fact some of them are wrong; T7 will never have triple drop with Sage, T11 will never have 4. Only T12/T13 have a chance for a 4 DB drop (12% and 25%, respectively).
I hope to have finished my runs and tests on the weekend and hopefully will release some videos then with lots of different numbers. Basically, Sage's sets builds for maximizing DBs should be run at T8, T10, or T11.
Note that a Sage's build is pointless on T12/T13. The Sage's set doesn't *double* the amount of DBs but just adds +1, so the additional DB drops on the highest difficulties are basically a waste for this set. T11 is the highest difficulty that is reasonable to run with a Sage's set, going higher is just inefficient and will not increase your DB/h.

I tested a few DB builds recently, including wizard builds, see here:
