At some point I want to do some experiments regarding rotating weight or have someone who knows math/physics + cycling do some number crunching. Theoretical only gets so far, like the physicist that did some calculations regarding a particular NASCAR race. He figured that based on the curve etc of a particular track the max speed of the cars would be 165 mph. The actual speeds were 163-167 mph so he was pretty close. He also points out that the quickest 0-60 times for cars should be in the high 2 second mark, based on the assumption that it would be hard to get more than 1:1 coefficient of friction between tires and pavement. His assumptions fall short here and there and there's a lot of hoopla on how dumb he is but those making the calls aren't taking his assumptions into consideration (1:1 coefficient of friction, no aero factors involved; once you negate those assumptions then obviously his calculations go out the window, or you have to recalculate to get new values). Anyway theoretical is good but I want to see how weight affects acceleration at high wattages, where 50 or even 100w is not that significant in the scheme of things, meaning it'd be 5-10% of total, not 30% or something. At 1000-1200w 50w is close to the margin of error, i.e. statistically not significant. That's what I want to test.
