In theory yes. Back on earth: I can argue that each task is 13 points. Usually this goes to being a pissing contest. The person that is deeply familiar with what needs to happen and has written this down (assuming written down not a one line to fix somthing) to be "estimated" probably is in the best position to acually do it/fix it. Also it's an insidious way to get the drones to fight each other trying to one up and show how smart they are. The person assigned to fixing it should estimate it (ie I have completely silenced "10x" developers by just telling them to just pick it up and do it if it's so easy).
