Hello all, ran into a snare last game. My DM doesn't believe that Brains Over Brawn applies to Initiative checks. So I need to compile all the Factotum rulings from sages and what not to convince him or avoid any other problems.

So, does anyone know where I can find the ruling that allows BoB to apply to initiative check?
The ruling that states a Factotum refreshes his inspiration points per encounter or "with one minute rest in between"?
and perhaps other rulings that are controversial that I may have missed and therefore don't know how to search for? And has anybody else had this kind of problem? Thank you in advanced.
