Interesting stuff.
I use a combination of patterns on my keyboard, random substitution of punctuation, numerals, and capitals, and an associated phrase word.
P1 standard W2 as my reminder tells me everything I need to know about my password.
But, that one is a short password, fewer than 20 total characters, so I only us it on systems that require 2 factor authentication.
For systems that don't require 2 factor my passwords are a LOT longer, but still pattern based.
