Nice idea! I naturally worry a bit that the reader's eye will have a hard time tracking which segment it should be looking at next (say they accidentally jump from 1 --> 3 for example). But like you said, if you used the horizontal rule between say 1/2 and 3/4, and just had whitespace between 1/2, it might be distinctive enough for a fluid reading. Thanks for the tip. I'll draw up a prototype.
