Some of us CANNOT close it off all the way or we loose a good useable burning temperature. Mine comes all the way out and a nudge back in will sustain a hot fire plus leave enough hot coals for relighting in the morning. If I take the time to load it right before retiring, I'll find a well charred log buried in the back which really helps get things going in the morning. You can tell by how dirty your window is in the morning whether or not you're leaving enough air on.

Agreed. Every setup has its own sweet spot after the wood is charred and the temps are brought up.
If I shut my primary air all of the way off, my temp drops, secondary burn ceases, and I get smoke out of my
stack. At 75-80% closed, I get an increase in temperatures with leveling off, sustained secondary burn, and a
smoke-free stack. At 40-50% closed, I get temps rising too fast and wood burning too fast.
