That's really interesting, thanks for the numbers and thermal view! I did not try that and am surprised there is not more of a difference shown here. Mine was purchased last year. I do see some reviews of my model with people complaining about the same thing but it's drowned out by positive reviews.
I wonder if there is more inconsistent behavior with mine, or the pan somehow? I have an unmarked 12" pan that is thicker cast iron with higher sides, and another 12" from Lodge that is thinner with shorter sides. I do notice it more with my unmarked pan, like it can't keep up somehow.
Keep me posted! Curious what yours shows next time you are cooking!
I just like watching Saru walk, the hand-arm sway is mesmerizing!
