The DIY projects I hate the most and fear are electrical projects although I've gotten very good at replacing bad wall plugs, GFCI wall outlets, light switches, and outdoor house lights, including motion detector flood lights. But fooling around with any of the electronics of my MES scares me so many times I've thought I fixed something electrical or electronic only to have it fail to work again. I looked at your technical explanation of what you did and it reminded me why I took no hard science classes ever in college and only took an Electronics 101 class (which I aced) as a night class in jr. college when I decided to go back and learn something new.
While looking at my ET-733 and looking at the temp swings I figured that the controller was maintaining an average of 235 degrees because the temp never went above or below a certain point in its swings. And the gorgeous ribs I pulled out after 6 hours proved that everything had been fine all along.
