This test for a bypassing divider plate is extremely easy (an infrared thermometer is usually sufficient) and very quick. In my opinion a quick and easy way to verify, or rule out, the possibility. At least on a large amount of bypass. Not sure about a small amount, but I think it would provide some evidence. In fact, I make this a normal part of a run inspection.
