Some of you would be experts don't know much about on time statistics do you? The IATA standard for on time is within 15 minutes of scheduled departure. Most Airlines around the world use this criteria. JAL use 30 mins and there may be others. You can rant and rave all you want, it's irrelevant. The stats are on the board and more importantly they are official. If you knew anything about ACARS you would know that those figures can be fudged simply by releasing the park brake. There is always the possibilty for pilot's to fudge figures, for a minute or so here and there , but not 15 mins. Suggest you find some other dead horse to flog!
