Perhaps someone remembers this article and can repost it, as there will be lots of questions about cooking prime rib in the next couple weeks.
I recently saw a good eats re-run when Alton did a rib roast (in the oven)
And he said in the episode that searing it initially damages the proteins rapidly causing them to release water - making the roast less juicy.
I'm with Gore and the lower temp and getting an even cook throughout, this was a New York Roast I did for about 3 hours at 215
Perfect all the way through
