I'm kinda with Sheldon on this one - from a scientific perspective at least. Bicycle gearing is a system of levers and pulleys that magnify the input (arc distance travelled by pedal) to give an output (distance travelled by bike). The best ideal measure that takes into account all of the devices - including crank length - is the ratio of input to output. Anything else is incomplete.
And do I use that ideal ratio? Of course I don't. I use gear inches.
