Taking a low side reading at idle is not really a functional test. You need to bring the engine speed to 1500-2000 RPM to see what's happening. If the low side drops and you still have a warm accumulator, then you have a restriction somewhere. Since the car gets cold initially, a low charge is not likely.

A restriction will be evident by noting frost or sweating on its low side and dryness behind it. You fail to mention the temperature of the high-side pipe immediately after the orifice and further up at the evaporator inlet.
