Fascinating discussion, Of Troy.

Your range is tidal.

I am particularly interested in this:

"So in the 'middle 2 hours'(1/3 of the time) 6/12ths (or 1/2) of the volume of water is moved!"

I can't help but wonder if this 'wave' phenomenon doesn't find expression in other waves including 'waves' in the marketplace where the acceptance of a consumer product, like a cell phone, achieves "critical mass" somewhere, perhaps, in the middle of its trajectory, after the "early adopters" phase, and long before the "market saturation" phase.

Mathematical whizzes are known to have applied "chaos theory" to the stock market successfully.
