One doesnt' have to be autistic to think in this manner. I'm convinced RM's "code" was unique and the key known only to him. It's not medical abbreviations or stock abbreviations (I played around with idea that very early on.) Sure, we can match up the letters with known abbrevations, but then can we put them together in a way that makes sense? Not just in one line, but in a way that follows throughout an entire page or large section of a page? There are very definite patterns in RM's writings. The way to solve the code is not one phrase at a time, but by looking over one entire page at a time and noting the patterns and the relationship between the letters and letter groups. I'm convinced there is a numerical scheme beneath the letters, and I still believe my solution posted in April and May is pretty close to being accurate. I also suggest everyone read Sammy Sheep's post from May 6th at 10:00 am for good insight.
