I understand where you're coming from Ron. I don't mess around with WB in the field either. I set mine on daylight, and leave it there. If I need to change it, it's a simple click of a button in my RAW converter. The reason I brought it up was because it could be the cause of the differences you are seeing. If you do another test, you should be able to check the color temperature in your RAW converter to see if they are exactly the same.
