Ok, so two follow up questions for you:Fday said:It makes sense to me that part time (or short duration) encouragement would be less than 100% effective and that people would sooner or later revert right back to where they were without continued reinforcement. That is in agreement with the studies and observations you mention.
The people that I personally know have used power cranks don't use them 100% of the time, of course, and it seems like you accept that. Given that is the case, we can assume that at some point a rider will use conventional cranks for some riding.
So let's assume that the rider does change over to conventional cranks for some period of time. Do you have any data from the period of time immediately after the changeover (presumably while the rider is still "under the influence" of power cranks), when presumably, their pedalling is close(r) to a perfect 50/50 balance, that says that the rider will put out more power on conventional cranks? Hopefully this data would be from a "downstream" power meter, i.e., not an ergomo.
Also, assuming the now continue to ride with conventional cranks, do you have any data that shows a power drop off with continued use of conventional cranks (when their balance presumably degenerates)?
