I'll humour you. Not sure why you think only league results reflect whether a rider is better than another??
The latest official 'rolling' averages, which I hate, show Scott on 6.56 and using your figure of 7.25 for Thorsell, makes it just a 14 point difference over the 20 meetings - so not even a point per meeting! I'm not sure but I think bonus points are also removed from average calculations?
I have not, nor will not, look back at those last 20 meetings to capture a) who the opposition was in each race b) who the team colleague was in each race c) the track/weather conditions for each meeting d) what each opposing rider scored in those meetings e) whether there were any injuries f) whether there any passes made in those heats g)whether there was any team riding in those heats h) the meeting scoreline at each heat so that we can see the pressure placed on the rider in those heats i)whether there were any tapes infringements, exclusions or mechanical failures.
I will then be in a more informed position. What makes us think one rider is better than another is subjective and not simply about points scored. In any case, I am not arguing that one rider or another is better than another, simply pointing out why it's not simple. My contention with your argument is that you said that Nicholls was "far weaker" than Thorsell. I disagree.
