What some mechanics do is, to spray the whole radiator with water. If there are cool spots. The water will still be present on those spots. The coolant circulating will evaporate or burn off the water. 20 degrees F difference on one side might be due to the upper radiator hose coming in from the driver's side on top. You might be reading that instead, of spots on the radiator. You do not need to necessarily have to drive for half an hour either. Do it when idle when, the car gets to operationg temp. What is the problem to analyze the radiator?
