I have the same pump. It's a common one,

because it's inexpensive and works well.
Possibilities:
- loss of a small amount of air when disconnecting pump
- shock--pump pressure equalization when connecting pump
- slow leak from shock
- gauge hysteresis or inaccuracy
At a guess, I'd rate them in that order
of likelihood.
I think you are right because "slow leak from
shock", wouldn't that mean the chamber would be
*empty* pretty soon?
So if we believe in your reasons 1 and 2, what
is the implication of that? Say you want
120psi, maybe you should put in 120psi and then
some - 125psi?
