Ok, now we are totaly off topic and getting a Ritchie seminar. That's a good deal. As long as we aren't pretending to answer the OP's question, there is always lots of stuff to learn from those who know.

Just to be evil, I did detect at one point in the above the sense that maybe there is not only a criterium frame but actually one for people who are good and another for people that suck. For those of us far enough back there may even be types that provide sales space for popcorn and chessnuts. I'm confused (yeah, right) but nothing hangs on it for me.
