How do they determine the "best layout" at the top? I pasted in a couple hundred lines of code and it claims that Colemak is the best, but Arensito (hadn't heard of it before) has fewer meters traveled and more home row usage (where Colemak is beat by everything except QWERTY).
At any rate, all the layouts other than QWERTY and Personalized were within 10 percent of each other for meters traveled.
In my case, Colemak was declared the best even though Capewell had less travel—because, I believe, Colemak had a considerably greater proportion of index-finger use. I reckon that because the Personalized layout clearly aims for maximum index finger use, with a slight favor on the right.
