Thanks Gabel.
FYI, for anyone who doesn't know, The best way to determine the ratio is to count the number of teeth. I just received my Boss gears and for the numerically low ratio (for hardwood), there a are 24 teeth on the chuck shaft gear, and 14 teeth on the handle shaft gear. So you would call this a 14:24 ratio, or to simplify it, 14/24=.58, so the ratio would be .58:1, for every 1 turn of the handles, the bit rotates .58 of a turn.

For the softwood side of the Boss, the ratio is 16:12, which equals 1.33:1 (rounding). For 1 turn of the handles, the bit rotates 1.33 times.

I guess if I want to make a chart, handle length should also be included, perpendicular distance from the center line of handle arm shaft to center line of the handle/knob pivot shaft.
