Jim,
I think what Theo is saying is that the speedometer/odometer is a single
unit and, if self-consistent, should be left as is. You could adjust the
speedometer part, but then the odometer would still be wrong. The only way
to do this right is to find a set of drive gears that gives the correct
number of turns per 1/100 of a mile (52.8 feet) as Laifman has described.
If you had noticed what the odometer readings were on your trip, and they
were accurate and only your speed was wrong, then indeed your speedometer
needs recalibrating. But if your odometer also reads about 10% high, then
don't touch it.
