Check the pressure after some usage periodically to see if it maintains the proper pressure. If the system cools the car more effectively initially then you've narrowed down the problem. If the pressure drops over time and the AC becomes less effective then you've got a leak somewhere that is letting coolant escape.

FWIW a gauge set can't tell you how much refrigerant is in the system by weight.
