Interresting but...
Wouldn't work for me.Not how i roll and would make my life a nightmare. At my "peak" i was keeping about fifty or so moderate to long alphanumeric usernames/passwords in my head. Occasionally i'd mix a user/pass, but i'd remember them all.
All of them were generated by KeePass, but the decisive factor came after. I had to read and type them to see if they "felt right". If they didn't, i'd try to "fix" them because i could "feel" where the wrong part was. If they did, no more work needed. It is my honest belief that passwords can feel "right" or "wrong" to different people thus making them easier/harder to memorize.
While this might seem a bit esoteric, i'm pretty sure there is an underlying explanation as to why certain random sequences "feel" different..
Probably the same underlying mechanism that makes certain note/chords sequences "feel right" when listened to and others be just noise.
