I would further hazard a guess that reasonably active APC posters comprise a small percentage of any given airline. I would say a ~2% to 5% slice of the pilot group. The other 95% or so are less critically inclined than APC posters. They have better things to do than post on APC. (spend time on hobbies or spend countless hours on the computer massaging their schedule, etc.) Or they just might fly their line, deal with the deck of cards dealt them, and enjoy whatever there is to be enjoyed.
