Yeah, the problem of rare and super rare dragons worried me quite a bit, but my reasoning is, first of all (as you said) we don't know the exact rate, and secondly, because they are rare, and so even if you get insane luck and breed lots of rares, your luck will probably eventually change, so you should cherish them (I know, it's just an excuse, but meh).

I finished calculating all the average Common breed times and here are the results:

Most economic: Fruitful Dragon & Charm Dragon (as before, since the White Dragons have very high coin rates)

Lowest average Common breed times (without Diamond color): Love Dragon & Island Dragon, with an average time of 9.6 hours

Lowest average Common breed times (with Diamond color): Crusader Dragon & Fuzzy Dragon, with an amazing average time of 5 and 1/3 hours

I'm not going to bother with the rare, super rare, and ultra rare times, but feel free to add them if you want :). I'm going to go edit the Diamond Dragon and Infinity Dragon pages.
