What is the RLC-100's accuracy tolerance of the speedometer function!
Reason i'm asking at say 60MPH on cruise on a level highway, the RLC will read 1 to 2 MPH faster than two of my vehicle's speedometers.
Same with the Escort 9500ix's when i had em.
Starting to think maybe the speedometers on vehicles are purposely calibrated a little slower as a safety factor for Law Enforcement purposes. Or maybe its differing or a little worn tire diameters?
