Weather was not kind today so i did a quick 1000F IR grill on a 2 inch ribeye and filet. They were small portions, not full size. My initial observation is once you reach 5 deg below target temp, drop oven temp 10 deg below target temp. I was shooting for 132F then hold for a few hours. I over shot to 134F which is perfectly fine, but just something to keep an eye on.
This was a "forward sear" The IT was around 80F after a 2 minute grill/sear on the 1000F IR grill. Just enough to get some good char grill marks.
