Navel Gazing, Graphine? Uh, Yeah.

On page 98 of this grammar, they give the list of every syllable that is represented by a single graphine. Most of those distinctions are relating to tone. I think sometimes con-langers do actually go get too obsessed with making sure all the phonemes are distinct in their writing system. And looking at the syllabary, um, it looks really weird. But if it works fine for native speakers then I don't think it's that big a deal.
