It isn’t surprising they almost all can achieve a higher than minimum standard by completion, and then can head off into the right seat of Q400 or bigger with a minimum of fuss.
I don’t think a lot of people see the big advantage in that environment.
Most parts of the world put 250 hour pilots in the RHS of Dash/ATRs etc. It's not a big deal as it isn't the space shuttle. QGPA isnt exceptional for achieving that.
