Watching A/C pressures is a very dynamic situation. Its very hard to comment without seeing the whole condition.

Your high side pressures are low which could indicate that you are still undercharged. But, your low side pressures are slightly high which contradicts. Were your aux fans running? Hold the rpm to 2000 for 30 secs. If your low side drops down to 20psi add 4ozs and try again. Unfortunately if you are doing this the car will heat up and cause undo influence on the pressures. This is why the refrigerant should be precisely measured to determine the state of charge.
