So for the first time ever I was watching my speed as I rode along a flat stretch. I leaned forward into the drops, and without a change in my cadence, my speed rose more than 1 mph. Then, I focused on spinning in circles and my speed rose again to more than 19mph with no increase in cadence and very little perceptible increase in effort.

Unfortunately this makes no physical sense... Same cadence, same gear = same speed. You have to spin the gear faster to go faster, they are connected by a chain to the wheel. As long as your cadence and gears remain the same, your speed stays the same... it is drag independent.
