Why give them the MPH? Thats a bad indication for the entire speedo range. if you tell them 4.5% they can figure out the difference at all the other speeds.
at 10mph its only .45mph off
at 70mph its 3.15 mph off
at 100mph its 4.5 mph off
sure you can just say ok well 2.7 is CLOSE through the entire sweep of the speedo, but thats inaccurate.
