Super Heroes don't fly airplanes.

The pilots who could best deal with an upset of a Dash8-Q400 are the pilots who fly Dash8-Q400s 80 to 100 hours per month. That kind of familiarity is worth much more than any test pilot training program.

That's exactly the problem here. People are taking one data point and making that airspeed causal when we don't know where that data point fits into the upset time-line. With a pitch-up of 31° ANU, and the known descent profile, it's obvious that they ended up very slow but we have no idea if that was a cause or a result of the upset.

Even if we had enough information to say that they were "too slow", whatever that number might be, before the upset that still doesn't tell us WHY they were too slow. Being too slow could be the result of the ultimate proximate event which led to the upset, not the proximate event itself.

While there's a lot to be learned about this accident, and general flying issues, from discussing this information, don't you find it a bit strange that a number of non-pilots are trying to convince us career professional pilots that they've figure out the cause before we did?
