Well, that pretty much confirms that the temp should only go to where you set the dial to. FYI, I never set to a higher than normal temp. I have found that when using the Guru in Ramp mode and setting the initial temp to around 225° or 230°, any fat that was not rendered in the plateau is gently rendered while slowly being brought up to around 200° giving me a moist final product. (Cooking butts here) It does, however, take a while longer but I have found that if I have the time, it's well worth the wait. One downfall is that I have yet to be able to complete a butt cook with the Guru in ramp mode on one load of fuel :-( .
