Don't forget that you can only adjust the pressure upward while the
manometer is connected -- adjusting downward will appear to have no effect
because gas at the higher pressure is already in the system.  If you
overshoot, you have to back off the regulator screw, then disconnect the
manometer to release the pressure before reapplying it for another
measurement.  Or you could rig up some sort of constant-bleed
arrangement.  Prolly should put out the cigar...
