Typemax 2.0 1KC base layout preview

Note1: orientation below is with Twiddler back in palm keys facing out (right or left handed)
Note2: all scores below are in 1000th of a percentage of all bigrams e.g. 1041 = 1.041% of all bigrams occurences
Note3: SPACE frequency calculated as follows: average 4.79 letters per word => 1 space for every 4.79 letters => 1/5.79 characters = 17.3% spaces => 4.79/5.79 = 82.7% letters
Note4: percentage-scores are normalized against frequency of SPACE (17.3% of all letters) to compute total load since http://norvig.com/mayzner.html does not provide letter percentages including SPACE e.g. E => 12.49% * (1-0.173=0.827) = 10.33% including SPACE

Note5: H uncommonly starts a word and rarely ends a word to facilitate SPACE -> H slide
Note6: N rarely starts a word and uncommonly ends a word to facilitate N -> SPACE slide
Note7: top 29 bigrams (th,he,in,etc) and top 17 trigrams (the,and,etc) are one-key-chord (1KC) stride (ie natural ngrams) except ing
Note8: inner mouse button is left unassigned for wider device compatibility and to avoid "scrunch" that occurs when pressing it
Note9: device should be positioned so that E(OOOL) is pinky "home" (instead of OOOM)

Alt 1: only middle mouse button
