Could you confirm if the temps went down immediately after changing the oil or over time?

Immediately. I drove around last night again and it stayed around 200F. With a bit of "spirited" driving, it went up near 220F, but it does for the most part stay around 200F.
Could be weather related too, temps outside have been a bit lower than before I changed my oil - but, not enough (I would think), to justify the difference.
Also, on break-in, I've got 1356 miles on it as of last night...
