In an ideal world and car condition, the pressures would tell you everything but there are dozens of things that will change pressure readings, especially with cars that have 2 speed fans and there is actually no accurate way to know a system is full except to completely drain it, evacuate the system of all air and charge it with the exact specified weight of refrigerant.
