Dave,

What in the world does my name or race results have to do with anything? Do we need the race results from John Cobb, Robert Chung, Andy Francioni, or Jim Martin to trust their ability to understand the science of measuring aerodynamics or cycling mechanics? I've got a BS in Biology from Cornell where I did physiological testing in cycling with Jim Hartshorn, a masters in science from the University of Rochester. You seem to define yourself by your race results and national ranking. Just for grins do a search on your name and "ranking". You brag about it constantly and backhandedly or not so backhandedly put all others down as you're doing in the most recent post. You frequently call others bullies yet you yourself bully every time you put others down by bragging about "kicking their butts" You may enjoy sharing all your personal details with the world but I for one do not.

My concern with you, a supposed engineer by training, is your complete lack of the use of any sort of scientific methodology in your supposed crank length experiment. Even though it's been pointed out to you numerous times that to actually compare different crank lengths you need to use the same gain ratios you've chosen to ignore that incredibly important point and just bulldozed along with "they were terrible for me". You seem to be proud of the fact that you used a 16 cog for testing your max watts with the 220s as well as 175s when you really should have been running about a 20 tooth cog with the 175s. Just for grins, go back and try the 220s with a 12 tooth cog and see how that works out.

So keep bragging about your results and how you'll kick my butt if we raced but please of please consider the science before you pop off as if you're an expert on every topic under the sun.

Rant over,

Hugh
