I would have thought that applying the formula of 2piR to the wheels on the wheelchair would have made more sense? One bit of tape to count rotations, a diameter of the wheel and a pocket calculator.... problem solved!So rather than get a tool that gives very precise measurements to 1,000+ yards and has proven to be instrumental in the precision rifle world (LRF), you got a measuring wheel???
Wow....just, wow....
Or measure in smoots.
