You can't accurately determine how much refrigerant is in a system by looking at pressures. There are far too many things that will effect pressure readings. The only way to resolve this is to completely evacuate the system and recharge it with the EXACT WEIGHED charge of refrigerant. Too much is just as bad as too little. The charge has to be accurate to within 2 tenths of an ounce.
