Lexzene always reads low so I inflate a bit more. Check with gauge. Checking with my gauge doesn't lose air vs attaching pumps. Though, if I am real careful and steady attaching, no air loss. Pull head straight off after inflation, just a hint of a hiss. No biggie.
Makes sense, assuming the gauge has an air release button, so you can make it a habit to intentionally over-inflate with the pump, and then use the gauge to release down to desired pressure. Otherwise you're playing a game of attaching pump and guessing how much to add after having read the gauge, and then we're back to wondering how much air is lost attaching that pump?
FYI, I think no matter how careful you are attaching your pump, you'll lose some air into at the least the pump's hose -- I think that's unavoidable, unless you're talking about a minipump that attaches right at the base of the pump and has no hose.
