I stand corrected to both of you.

GPS speedo's are the most accurate measure of speed on the water.

GPS has instances when it's not 100% accurate.

GPS measures distance between a straight line, or multiple straight lines. If you have slight arc to your path, your GPS is only measuring speed between (let's say) 100 ft. distance increments on that arc. That said you could be running 120 mph in a slightly arced curve, but the measured distances of GPS increments could indicate your SOG to be 122 mph.

Radar and Laser also have their discrepancies.

In this picture, the BLUE path is the actual path of the boat at 120mph actual speed over ground.

The RED path and points are where the GPS speed is measured, which in theory could be an overall computed speed of 122mph.

Now I am not claiming or accusing any wrongdoing or underlying agenda by ANYONE here. I am just telling you how GPS works.

This is one of the reasons why Kilo runs and other speed records are done in 2 directions, not to mention wind and current; measured by GPS, Radar/Laser, and other timing trigger systems similar to VASCAR.

Next we can discuss the red pill vs. the blue pill, and an airplane on a treadmill.
