so the difference is not measurable? but the athletes body senses it? despite cadence being the same, speed being the same, stop watch reads the same and power is the same? what exactly is the athlete sensing?
the earlier comparison to saddle height doesn't really work for me.
i recently tested out a new frame. on my first track day (after a few roller sessions) i sensed that my saddle slipped. i pulled in and confirmed that my saddle had in fact slipped. I was able to confirm this with a very simple measuring device called a tape measure.. I sensed the change- and was able to measure the change. about 1.5mm..
