We didn't ask folks for their predicted times because, well.... In the move to the new registration system, I forgot to include it. DOH!
As for sorting by state, it is a mixed bag. Somebody in Colorado can go to run their qualifier in Texas for an instant speed boost. Even within a state, some routes are dowhill, some are flat, some are mixed. Then you have the entire trail vs road issue since a "trail" in some parts of the country are just 12' wide roads (and each year we have folks who look at Barr Trail and wonder what they signed up for since they are used to running on wide, groomed gravel "trails" and not a rocky singletrack.)
Ultimately, the prediction system was mostly for giggles. What what really helps is looking at the 2015 stats by qualifying time which has the final results posted and going from there.
