The Lady who gave the presentation at the CF cert was using 500 m to measure power to weight for the CF athletes. When somebody asked what the highest recorded ratio was she said lance and 4.1. I assume it was over a 500 m distance that probably did'nt take very long at all. But then you know what they say about assumptions.
BTW Neal you're free to hang out with whomever you choose I just know that if I had such high standards I would'nt have any friends at all.
