Switched from guessing at sealed system pressures to a $12 analog gauge set from a pawn shop in Reno
Spent 6 months charging by feel and redoing jobs twice, now I pull a vacuum first every single time. Any of you still trust the touch method on old R-22 units?

Ha, I still see old timers doing the touch test on R-22 and honestly sometimes it works. But I watched a guy frost up a compressor last summer because he swore his hand knew better than a gauge. Twelve bucks at a pawn shop beats a $400 call back any day. I pull a vacuum every time now too, even on the old clunkers. Feels slow in the moment but it saves you hours later.
