Have you ever heard of "vowel compressibility" a.k.a. disemvoweling? It's possible to drop all vowels while still being able to figure out original decompressed word. Ex: irrelevance -> irrlvnce ... you'd still have to type first and last character. Certain suffixes and prefixes can be stored in piano memory. Ex: length("IRRLVNCE") = 8 < 10 fingers => 2 chords [1 typing maneuver] over 2 octaves

I'm using a piano keyboard. If you chord, you'll be able to increase WPM by typing whole words in one motion.

By the way, there's a bug in average WPM calculation function. My average WPM is nowhere near 199.99!
