Whether you're going downhill, uphill or whatever, your counter sprocket will always rotate at the same ratio relative to the rear sprocket because they are directly linked through the chain. Yes, it does take less POWER to achieve XX MPH downhill, however, the sprocket rotation RPMs are the same.

My uphill/downhill/wind comment was to account for the more RPM or less RPM that would be required to reach an ACTUAL speed (the radar), not an indicated speed (on the speedo). This error, however minute, would contribute (however infinitesimally) to explaining the reason why I may have gotten a broad range of 11-15% error.

RE: sprocket

i got a Vortex. as far as why, I thought it's pretty respectable brand from what i've heard and asked around.
the speedo is way off. i was out riding today and that thing said 135 and i know i wasn't going that fast.
