Ironic, me ! I do keep records, and they are very copious. Also I keep to all the road speed limits unless I am in a tearing hurry when I assume my speedo is over reading by 10% and knock off 3% safety factor so that indicated 75.4 mph becomes a genuinely safe 70 mph. If I am on a dual carriage way in North Wales I assume my speedo is over reading by 8% and knock off only 2.3% so that indicated 74.3 mph equals 70 mph. Beeky - how's my arithmetic
