I'm generally quite good with math of any sort, and graphs are usually easy for me to decipher.

Unfortunately, I have no idea what your charts are supposed to show; sorry.

What would be a useful chart, I think, would be to show the gear ratios (either in inches or in front/rear) for each. Given that a 3x9 or 3x10 has about twice the gear ratios of the 1x14, it would seem likely, to me, that the 3x9 or 3x10 gives a far more nuanced ability to find the right gear, and (as you stated) it gives the ability to make a large shift (shifting the front ring) or a much smaller shift (shifting the rear); or even (with my brifters) choosing between downsshifting one, two or three rear gears.

I don't particularly enjoy the shifts that require simultaneous shifting of the front and the rear, so I certainly can appreciate the benefit of a truly linear gear-train. But I have a hard time believing that the Eagle has the same ability to have close-ratio shifting as a 3x9 or 3x10, which you seem to be suggesting.
