I have a well tank with bladder. I recall something about the amount
needs to be 2 lbs more or is it 2 lbs less than the turn ON switch
setting. Which is it? My switch turns on at 31 and off at 48. The
pump is cycling constantly when I turn on the water, so the air
pressure must be way off. Just to fill the toilet tank, the pump goes
on and off at least 4 times, and that's like 5 gallons or so.

The cycling indicates the tank is almost waterlogged. There's almost
surely a small leak in the bladder. Best you can do is to drain it
completely and start over again. If it isn't too big a leak and there
isn't too much water on the bubble side, it'll function ok again for a
while, but a new tank is in your (relatively near) future in all likelihood.

It should be 2 lb below when empty.
