For one thing, Robin appeared a few times in 3A, then appears more often in 3B before he became a regular in the rest of the seasons.

Same thing with Ruby when she appeared a few times in 5A and may appear more often in 5B. And possibly she might become a regular again in the next season. Who knows. Nice theory, but we can't use math and logic with a tv show. Red was a regular and will likely not ever be a regular again. No reason to as she has one storyline and that's with recurring characters, not regulars. Robin is a regular's love interest and around regulars, so it made sense fot him to become a regular. Whatever happens, guess we'll just have to wait and see.
