Smart cat, Paul (as many of them are).
I tried out a Kenji Lopez-Alt recipe for our tenderloin last night (as posted on Serious Eats). This involved salting the meat the night before, doing a long, slow roast, and then finishing under the broiler for a reverse sear. I'm always suspicious of his recipes as in my experience, there's always something in them that isn't quite right, or at least doesn't work out right for me. I checked the comments, and sure enough, in this one it's the amount of time you can expect to roast the beef. He puts it down as 2 hours for a trimmed and tied 4 lb. tenderloin. A bunch of people described checking on meat's temperature at 1-1/2 hours and finding it well beyond what they wanted. Otherwise, though, reviews were absolutely glowing.
So I started on Christmas Eve by drying off the tenderloin (which had been trimmed and tied by the butcher), placing it on a rack over a sheet pan, salting the hell out of it, and putting it in the fridge uncovered. Yesterday around 2:00, I took it out of the fridge to warm to room temp. At 3:30 or so, I dusted it with pepper and powdered porcini mushroom, which I will insure is sealed and tucked away should you come visit, Jenise! I then put the sheet pan, rack, and meat into our oven at 225 with a Meater thermometer in it to monitor the temp. I was shooting for about 128, since the overshoot on the temp and the broiling would take it to a bit under 135, which is medium rare (according to Kenji, which I note is different from yours, Karen). Sure enough, it took a bit over an hour to hit 128. I took it out and tented it for 20 minutes or so while we finished side dishes and the broiler heated. Then it went back in the oven, under the broiler, for around 5 minutes a side while I monitored it anxiously and turned it. When it looked like there was a nice crust, I pulled it out and rested it another 5 minutes or so (although Kenji says this isn't really necessary). It turned out beautifully, with a very even rosy pink from center to edge and a decent crust on the outside. The meat was melt-in-your-mouth tender and fairly well flavored - especially for tenderloin. One slight issue was that the thicker end of the roast was rare rather than medium rare, but this did give folks a choice and we had a couple of rare meat fans. Also, I think I was a little conservative in the time under the broiler. If I do this again, I'll let it sit under there longer. Overall, a big success and I'm always happy when I don't screw up a pricey piece of meat.
By the way, Karen, your recipe sounds excellent as well. Thanks for posting that - I might try it next time.
