Yeah, I would think. Did you also have to pass a commercial checkride at
the end of the 12 hours? I would think you would want to be more than (in
your words) "more or less comfortable with the added workload and speed"
before you had to pass a checkride, with all of the added pressures and
nervousness that "automatically" comes with a checkride.
