Tail harm

Look at the worst outcome anyone actually suffered, not the typical one. Ask how bad it gets at the far edge for the unluckiest few, and whether that severity is survivable, regardless of how rare it is.

Example

In the course, the tail is not a lower grade. One blind student paid $1,200, could not finish a single week-one exercise, missed the 14-day refund window, and lost the certification her employer required. That is the loss to size, not the 82% average.
