When it happened - I just made a mental note of it and changed the oil a little sooner. And I used a good synthetic oil.

I wouldn't argue that - oil performance does deteriorate with increased temperature. However, it starts to deteriorate at distilation which with modern oils normaly happens >350F with dino (higher with synthetics). Like you, I wouldn't think much of 320F and would probably change a little sooner afterward. Letting it cool down before turning it off os a good idea as it helps prevent coking.
