"Well, y'all have just about bench raced that thing 'til it needs an overhaul."
Ain't that the truth.
I'm working on a formula for a chart that nails tire (or tyre) slippage (but doesn't include clutch slippage?). It tracks temperature, humidity, angle of the sun to predict surface moisture gain or loss, distance influence of the canals, hours since last precipitation, tread pattern and tread depth of tires, quantity of tire plies (bias or radial), driveshaft angle, number of u-joints, tire pressure, tire loading because of a different driver, body heat retention because of basic color, shift of front to back weight bias due to fuel expended, pull of moon if available, and a few more things. I've got it worked out with line graphs intersecting a multitude of other graph lines and the basic graph paper lines. By god -- it's beautiful!!! Unfortunately my wife just pasted it on the back wall of the den. So it's not all for not.
