I only use lump and I can usually cook 5 or 6 hours without adjustments,... I wiggle first and often that brings me back to temp, but if that does not work in 10 minutes or so, I'll open a vent.
I've never run just a load of lump, but I would guess the cooker would operate differently without meat.
