I don't see anything unethical with speculating, if it can raise awareness among the pilot group about the inherent risks of some maneuvers.
The one thing that strikes me is the fairly tight circling, whether you call it a circling approach or a visual approach doesn't matter. If the maneuver was flown from the right hand seat the runway could be hard to see. The room for lateral or vertical deviations are small. In an attempt to get visual with the runway speed awareness is lost. Pulling back on the yoke may even be an abscent minded attempt at that.
