Webby - this could account for the day you & Alan came back from Kent together - and he was having to consistently travel at 100 - 110 to ride with you (not too much fun on a monster on the motorway for quite a few miles, and his arms had been stretched like a monkeys by the time he got home) - you said you hadnt been over 90 that day.
Alans Lawson consistently reads 17% less than the speed he is actually doing.

We usually use my bike as the 'speed guide' when each creation gets put on the road.
