To anticipate half a month's gross delay days per year is surely way outside the experience of the rest of the air transport world, especially as how such items are measured then gets subject to statistics manipulation.
It's also one of those things where, once such goals are set, people get into the way of accepting them as the norm. We had 15 days complete disorganisation in a year but we have "done our job to target". It's like security/immigration queue times. Once these were set as a "goal" of not more than 45 minutes, the perception comes that 45 minutes is the goal. "People waiting 30 minutes ? We're inside the target, a couple of you can go on an extra break".
