For what it's worth you didn't mention you ran a 1:08:xx HM on a legit course in August. That is a much better performance than the full you listed in your original post. It also looks like you were running way more than 45 miles per week leading up to that.
If I was Vegas I would out over/under on 2:20 for a lifetime PR if you really work on it over the next couple of years.
