Pretty common actually. Bandits are know to read about 10 MPH faster than real speed. The first time I saw this was on a RADAR warning sign at a construction site just outside of Ruidosa, NM. I believed I was "running at speed whicih might cause me to be selected for making a monetary contribution for the good of the State of NM; but the sign said, meh, probably not. Explains why a number of HPs have came after me!
I've checked with GPS and this is about right. Saved my bacon more than once! I ain't gonna change it!
