great question, jimbo, let me just chime in that this has been a great block for me when trying to evaluate the runners coming from europe that are trying dirt for the first or second time in north america. I'm consistently impressed with how accurate the european turf numbers are when strictly compared to north american turf numbers, but they definately don't compare to n. amercan dirt no's.
i'd really appreciate some imput from jb or allen. how do u get those european no's so accurate, and why don't they translate to dirt?
