Finger based metrics, as determined with Keyboard Layout Analyzer, using Patrick's original scoring model, and Den's first revised version.
We show the ranking Overall, for the broad Form Factor, and against other similar layouts (Peers), for English prose, assorted Programming, and Average of the two.
'Peers' means compared to other layouts with same characterics, e.g. ANSI/ISO vs Ergo, and matching 'Has letters on thumb', 'Uses AltGr for standard characters', 'Moves non-character keys (ANSI/ISO)', 'Changes shift pairs', 'Changes top row (ANSI/ISO)', and 'Uppercase on different key', as listed above.

This looks at how many words can be typed with only left or right hand. We want these numbers to be low.
This metric was done "strictly" ... shifted or AltGr letters were only included if Shift or AltGr was on the same hand.
Note: we exclude the Dvorak one-handed layouts comparison, since clearly by design they can type every possible word with one hand.

This is a weighted analysis of same-finger usage.
The probability that a letter will follow another given letter
is used to evaluate layouts by which letters pairs are on the same fingers. We multiply this figure by the percentage frequency of the first letter, in English.
We add the probabilities in both directions, for example "er" and "re".
There are some exceptions: We only look at lower case, and if the second letter is on the same key as the first, we ignore that pair.
The idea is to see how much a finger has to fly around, and if the two letters are on the same key (as in the split-case layouts) then it doesn't have to fly between them.
The metric does not measure how far the finger has to fly, just that it has to. I'll look at adding distance, row jumps, inward rolls, outward rolls, to this metric if possible.

"Fraser Street" (thanks Shai) is a specially-crafted text in which most of the words are typed with only the left hand, on the QWERTY layout.
It was designed to highlight how much better the Dvorak layout is at hand alternation.
We ignore spaces and punctuation.
