Guppy,
You can holler all you like about the merits of the procedure and how it is TERPS this and TERPS that, but I, as a pilot prohibited by my airline from shooting back-course procedures like Denti (Why is that?), living in a country where there is no provision for them (Why is that?), and having not done one in at least the last 4000 approaches (not flight hours - go figure the difference) found it, initially, could be interpreted, by myself, as ambiguous.
That being the case, I surmised, perhaps erroneously, that I might not be the only one who felt that way. Of course, the fact that previous contributors alerted me to that fact clouds the issue of causality.
So I went away and looked at some notes. Now I feel better and philosophically disabused.
However, I would suggest that the ambiguity of the plate is contingent on far more than your ability to mount a vociferous defence in its favour.
To this end try and understand my analogy(s) a little less literally.
