If the reported temp value accurately showed the real temp variations, the recteq support phone would be ringing off the hook with customers complaining about temp swings. I'm sure they have what's know as buffering (averaging) to make it appear the temp is stable so people don't freak out with minor temp swings. Do these minor temp swings effect the end product of your cooked food, no. We're using fire to cook food, it's doesn't need to be dead on accurate, just in the ball park, to put out good food. People tend to overthink things, it's a outdoor grillI recently purchased a Fireboard 2 Drive which is arguably considered the gold standard in temp monitoring. Out of curiosity, I used it to monitor my 590 temps on a dry run and have come to the conclusion RT controller and temp reporting is not nearly as good as advertised. I'm not dissing RT but, on warm up to 180 degrees it lagged 25 degrees behind the Fireboard in temp reporting. At 185 degrees on Fireboard, RT reporting 210 before it all settled down. I ran it for 4 hours and observed temp fluctuations of up to 17 degrees on the Fireboard. All while RT is reporting 225 with a new pit probe and the Fireboard probe mounted adjacent to the RT probe. I know nothing about the world of temperature controllers and reporting, but 17 degrees is nearly 10% reporting variance. Significant or not? All that to say the RT system and app graph are not accurately reporting what is actually going inside the grill.
