I hate to bump an old thread, but is this to suggest that the position of the number itself has nothing to do with how waze calculates if HNs are in order or not -- it's only the stop point?
I thought I tried this out and couldn't get it to work, but I might have to revisit. The house numbering system is just difficult enough that I tend to ignore it. You have to align the planets, stars, and decorative soaps in your bathroom just right to get the system to allow you to save the numbers without forcing them. ESPECIALLY on a split road
