I thought about the results thing, yeah. I guess you don't want to tweak the weights any more. But my main sentiment was about the color range in the image. It has a significant impact on people's perception.

In my head, it'd be rather nice to show the pinky home keys in the same color as the Curl home positions – the color of Nearly Full Home! And actually, the F and U too since those positions are very good. We love ridiculing QWERTY for putting E away from the home row but it's in fact a nearly-home position which any blindingly fast QWERTY typist will probably attest to. Depends a bit on finger lengths and wrist angles and natural curl and whatnot, though.

In the World Of Curl, the Holy Home Row is no longer straight and narrow, which makes both the upper middle finger and lower index finger positions better. So in sum, I'd suggest having six cyan keys: AO/FU/DH. :-)

I'd also use dark blue on the 2.5 weights. Because the middle finger curls are quite okay really, much better than the ring finger ones and more on par with those dark blue keys above.

To sink in the point a little further, I'd personally consider mixing in a little more green in the cyan. But maybe you're committed to a stricter color scheme.

On a side note: If the little finger home positions are cyan(-ish), what then about the ring fingers? Well, I agree with your weights. The ring fingers are stronger than the little fingers by a good margin, but interestingly they're a lot less independent. So their home positions are good, but their stretches not so much. The little fingers handle a lot of stretches quite dexterously, given their inferior strength! (But that still doesn't quite save the QZ etc positions.)
