The important timing is how long to FILL the tank to 52 psi from start at 24 or so. Measure that with no faucets open. If it fills "fast" the pump is ok, and then look for a bad filter somewhere in the system or a broken bladder or diaphragm in your pressure tank that is restricting outflow. Pretty much a certainty that your tank is shot.
I would set the pressure to 40-60 after you [probably] change the tank.
