So much new stuff in this thread!
1) I imagine another vulgar ratio would be the total number of dollars in a structured transaction with 'Kristen' divided by the number of sperm in a certain blue dress stain.
2) Did you know there are more transcendental numbers than rational numbers? I'm not sure if that will contribute to your peace of mind, however. If you like puzzles: Every year has at least one Friday the 13th. Can you prove it? (I had to do this on a number theory exam in college.)
3) The speed may be related to the issues I'm having with the Protege. The course does have some downhills that I go quite a bit faster on (likely in excess of 20mph near the bottom). However, it was 52 degrees and sunny for the remeasure, and a cloudy 46 for the original measurement, so temperature may play a significant role in lowering the computer misbehavior threshold (CMT).
4) The reason I don't use a Jones counter at present is that there is not a model I can purchase that fits on my bicycle wheel. The JO counter is too wide to fit. Count yourself lucky if you have one that fits.
5) My individual rides of the mile segments are pretty uniform but, again, I get pedestrians (and cars!) doing unexpected things in front of me that necessitate stopping and restarting. Since my bike has toe clips and the shoes I used are not well designed for clips (but they work great for keeping my feet warm!), I got a little more wobble than I would like when I started up again after many of these stops. I can guarantee you that I was not off by anywhere close to 120+ inches between 2 rides over the same mile segment.
Of course, it's only been about 22 years since I received the first certificate for a course I measured, so I may not be as sharp as I was back then.
