When looking for something else I chanced upon the attached which was my attempt at 2004 I did several years ago. It illustrates how it is possible to make the presentation rather clearer by spacing it out appropriately, joining the similar sequences together and using diagonal lines that helps particularly when a 3 apect sequence converges with a 4 aspect sequence to the same exit signal.
