I applaud your calculations...an accelerated stall, low familiarity with the plane by both pilots (possibly, not yet confirmed) and all starting at below 1000'agl.
flight instructors would prefer to practice stalls above 3000' and accelerated stalls even a bit higher.
and add a possible cross control at the moment of stall!
"stick and rudder" should be required reading for all pilots.
a chandelle, thought likely to break the class B airspace and possibly go into cloud might have been one way out...better to hit a cloud than a building, the on board collision avoidance device would have helped out for possible IFR traffic.
