Funny enough Rick, but ignoring class is your mistake. The host works overtime to provide quality integers, yet the better players here, employ those numbers and incorporate a variety of other variables, some offered, some not, such as workouts, pedigree, current form, etc.
While there is little argument against class being the biggest determinate of how a horse may finish, your stance against, whether above your pay grade, or your choice to ignore, is costing you at the windows; which many reading this relish.
As for horses being more comfortable outside it may be 66% or even 85%; ask someone for their opinion; who knows. Ten cents on the dollar they are in my range. bbb
