This was sort of what I was thinking as well.
Turn on the supply valve on your CO2 tank. Turn the regulator up to desired pressure. One thought here, if you overshoot your desired pressure, turn down your regulator a turn or so. Then pull the ring on the pressure relief valve on the keg. The pressure shown on the gauge will drop to the current setting. Now release the ring and turn the reg up slowly so that you creap up on the set point you want without overshooting.
What you may have done is overshot your pressure. When you turned down the regulator, if you did so without venting the pressure in the keg, the gauge would have falsely read higher than its setpoint. Over time, as the CO2 dissolved into solution, the pressure in the line would drop until it got to the regulator setpoint.

(Disclaimer: If it seems like I am rambling, it is the medication. But my advice is sound.... and makes perfect sense to me. )

16psi this morning. I'm going to chalk it up to poor gauges.

The other day it did go from 17 to 12. I must have had a small leak, but I tightened everything up. Now it went from 17 to 16 overnight. I'll attribute that to no leaks and a crappy gauge.

if i set my reg then put it an the tank in my keezer, I get a 10-20% drop in output pressure as it cools.......... a leak should not cause your pressure to drop if the gas is on, it will cause your tank to empty

I let my reg/tank chill overnight before setting pressures.
