If you KNEW that you had 30-45 minutes HNF and an hour or two low and slow....well then you could chill a bit :-).
The frequency the old hands check at gives some "feel for this"..........."check every 30 minutes after the IT hits 200f, pull when it probes like butter".
But if you cook HNF like some do, say 300, wrap in butcher paper after the first 4 hours, then check at some interval until it probes done, what happens if you leave it on an extra hour AFTER it probes done ??
Your Windows of time seem spot on to me. I have been on the anti "feels like butta" wagon for a while.
