Of course GPS is way more precise.
What irritates my mind is the thing that many say their bike runs over 6000 rpm at 70 mph. Referring to the calculations above, 70 mph should be at around 5600 rpm. This is almost 10% difference. Tacho and speedometer should be more precise. In fact his speedo has to show less than the reality, which is not typical. Or the tacho has to show more than reality, which... yeah, we should test it with a proper rpm measuring device.
Might worth some experimenting on this topic in the future...
