That is most likely to be a good reading, assuming that the temp near the suction service valve is similar. If say your suction pressure was 65 psi (which is likely) then the saturation temp is around 38F. A heat gain (super heat) of 10F which you would have, says that you have boiled all of the liquid R22 to gas in (or near) the evaporator and the vapor gained another 10F on the way to the condenser. Too cold would mean that you might be returning liquid because there was not enough work to do in the evaporator relative to the charge level/pressures. Now if say your suction pressure was 80 psi then your saturation temp would be 48F and you might be returning liquid R22 to the condenser because the line temp is the same and the phase change to gas might not be complete. The accumulator is there to accumulates liquid up to its rated capacity and only let gas leave but if you are over charged enough and overwhelm the accumulator them liquid can get into the compressor and kill it.
