>>Why do you need the programmer to estimate if you're going to ignore the prediction?

So the manager can pass the buck.

>>If programmers aren't even asked to estimate or ignored, obviously the problem is not that programmers are bad at estimating.

Yes. I would argue most of the time when projects take longer than predicted it wasn't the programmer's estimation that was the problem.

>>The method can fix some potentially harmful management<>programmer interactions. It can't fix stupid management.

Agreed
