Thanks for the detailed feedback. I think that it will be very informative to other runners in your category. You are the first one that I have ever heard that said doing the full treadmill simulation was easy. For those of us who take over twice as long as to complete, it is a real slog or grind.
Your times are really good. I previously did some comparisons of times on Matt's pace chart for different altitudes but at the same slope and concluded, if you did the simulation at sea level you would need to add 30 minutes to your time for altitude effects. But in your case, I think 30 minutes is too much and along with some other comments you provided, I think you may have a good chance to finish in the top 10. A lot depends on how the altitude affects you.
