In the 1960s I navigated for the late Dr David Dew-Hughes in his Chummy with a belt-drive speedo on the Eastern Rally, where navigation techniques were very similar to the Measham which I have done since.The first time I put some faith in the mileages shown on the odometer (inaccurate as it turned out) and we got a third class award. The following year with the belt broken, so no indication of speed or distance, I was telling David to slow down quite frequently, and my inspired guesswork got us a first class award, being very close to the required average speed. I still think that gut feel may be more use than accurate instruments.
