In defense of the Cortex system (which I've run in BSG a couple of times), the chance of rollong a 2 on 2d12 is 1/144, less than 1/7 the chance of rolling a 1 on a d20. Even the chance of rolling a 2 on 1d4+1d6 is less than rolling a 1 on a d20. The more dice you roll, the more likely the result falls in the middle of the possible range. That is, more dice=less random.Even with BDH (which I had), the system has some major problems with it that ruined it for us. I eventually basically ran the campaign systemless. In particular, what irritated me the most was the lack of a basic competence in checks. When you roll d12+d12 to do something, it's amazing how often you'll roll a 2.
It's sort of like the Hulk being unable to open a door whilst Rick Jones does it with ease... the system felt that random. And the random element was raised even higher by the addition of Story Points, which have a wackily minor effect, until the players worked out that the best way of using them was to spend them all at once.
(I assume this isn't the first time you've heard this but I'm bringing it up because it needs to be).
Also, later iterations of the system made plot points less random.
There does need to be an explicitly codified version of "taking 10" although the rules basically just say to use common sense on those sorts of things.
