Funny you should ask - this was one of the few times that I actually checked the internal temperature rather than going by touch, just because I was curious.

I removed it at 121 internal and let rest under foil for 5 minutes - so probably something close to 125.

Cook time went like this: Rest steak at room temp for 1 hour. Sear at 650 for 90 seconds per side (I was in a hurry, didn't wait for the higher sear temps), rest on counter for 20 minutes (not under foil), back on Egg for about 6.5 minutes per side at 400. Remove and let rest (now under foil) for 5 minutes. This was cooked on the Mini. The roast period was longer than usual because of the lower searing temps.

Hope this helps,
