Fair enough. You were thinking about the problem from the point of view of hiring a teacher; when projecting it onto the problem from the point of a teacher deciding how to teach, I had to make additional assumptions not in the original post (ie, that “teachers care about true performance to some degree”).
Still, I think that putting it in concrete terms like this helped me understand (and agree with) the basic idea.
