I have no idea which is more acurate grays' odometer, google maps, or GPS. they all have a margine of error. I accept my odometer as being good enough even though I could get better numbers by using Googe maps or GPS. My main consideration is the change/improvement over time/distance. a 20% improvement is still an improvement whether it is actualy 19% or 21% is less important to me.
