I plan to measure a 15km course in Ridgefield today, then drop my car off for service and ride home. It will be nice not to have to stop, remove the J/O counter, put it in a baggie and carry it home, to reduce the wear and tear from a long, higher speed ride.
I have an even greater advantage Jim; I own 4 bikes including 2 road bikes, a mtn bike and my old measuring bike that I only briefly used for regular cycling years ago (minus the counter).
I plan to replace my old Trek measuring bike w/a hybrid. I'll only use the new bike for measuring and'll feel more comfortable riding sitting upright on thicker tires (which'll also enable me to measure dirt roads w/peace of mind that I won't slip, fall and otherwise compromise the accuracy of the ride).
Today I did a preliminary measurement of a 10K course in Darien. I calibrated my bike, then switched my Protegé from "Bike 2" to "Bike 1" mode, rode to the course, switched back, measured, switched again, rode home, switched once more, and recalibrated.
It was nice not to have to remove and install the J/O counter for the faster, non-measurement portions of the ride, and nice to have them measured in "real" distance and speed (albeit metric).
I tried the "millionths of a mile" trick on my Protege 9.0. and the #2 setting did indeed read out in miles - but only to the nearest 1/10 mile.
I think I'll switch the #2 calibration to the real metric value, as it will give me a true readout to the nearest 1/100 km. I hope.
It looks like one is stuck with either metric or imperial for both #1 and #2. You can't have #1 be metric and #2 be imperial - at least my fiddling has not been able to find a way.

Jim: I don't know whether you noticed, but I describe in my latest write-up how you could have ridden to and from the course with the display in imperial units (ignoring the part of the screen that says KM/H). To do this you would have had to set the circumference to millionths of a mile/rev, calculated by dividing the setting in mm/rev (millionths of a km/rev) by 1.609.
Pete: Your reference to tenths concerns only the odometers, which read like this whether in overall metric or imperial mode. The trip meter always reads in hundreths. By using the "trick" it is perfectly possible to alernate between a hundreths of a km and a mile simply by pressing the circumference switch.
Obviously I overlooked something. Now that I am all calibrated in metric units I'll stay that way for a while. There's a lot of button-pushing to get things changed, and once it's done it's nice to relax.
Later - I reprogrammed it to millionths again. It does work as Neville says.

I'm going to give it a try, but I've become rather fond of metric readout - 30km/h sounds so much faster than 18.6 MPH, and the total distance is more impressive sounding, too. Plus, doing the mental conversions give me something to do on the ride.
