Niiice, that's a lot of buffs. But yeah, I know it could go a lot higher, I'm just being frugal with my buffs since I'll be Crimbo farming for a while yet. (I'm only running hair spray and serum of sarcasm + equipment (hooray Brimstone!))
That's why I only do about 60 advs (I did forget my brimstone boxers though!)
For about 150K I can run Purity of Spirit, Cock of the Walk, Superhuman Sarcasm, Gr8tness, Je Ne Seis Porqois, Tomato Power, Izchak's Blessing, Butt-Rock Hair, Towering Strength, Mitre Cut, Knight Life, The Royal We, Full of Wist, So Fresh and So Clean, No Worries, Stuck That Way, and probably stuff I'm forgetting for 60 advs. This also takes 2 fullness for the queen cookie effects. Either way, this gains me 1.5 levels per day, so far.
