There is something fundamental here.

Competent programmers make it look like they slack off and what they do is easy.

The ones who create problems that in practice only they can fix and seem blocked all the time are the ones that seem productive in an agile environment.

I guess that is the reason standups evolve into some sort of status update, finger pointing and bragging contest.
