Sounds pretty anal to me.


There's also the
risk of leaving the compressor powered up (and leaking), which is just
a sizable waste of energy.

Agreed on that one.

What if it takes my compressor a week or two to drain down, so there's a
sizable change I might use the energy? If I have half left, I use half
as much enegery refilling the tank.
