Oh sorry, but at what speed is it 8mph off? That would give you the percentage.
Like on my truck at an indicated 60, I am actually going 67, so about 11%, when I am driving without the GPS I just figure 10% since it is easy, 3mph at 30, 4mph at 40, etc.

It's 8mph, not 8% though. Ok, I'll have some coffee and after that I'll put the pen to it and see what happens.
