I really do not see that it would be "much clearer if it could have used mathemtical notation". As experienced programmers, we are used to reading linearized formulas, aren't we? And these particular formulas seem quite simple. Note that if and when this document is published as an RFC, the RFC Editor will supply some additional blank lines and clean up the indentation, which will make the equations much easier to read. Also, as you note, the ASCII art diagrams could really use a cleanup. They are unnecessarily ugly, kind of dyslexic. It is true that the discipline of ASCII art forces the author to give some thought to the clarity and modularity of the text. Opinions differ on whether this is a good thing or a bad thing.
