No offense but that is none of your business, and I am quite puzzled as to why you think it should be your business. As long as someone isn't using a bot or otherwise circumventing the CBA, who the hell cares? Some people bust their cajones over the summer so that they can take the whole month off come October, as an example. Some people are accustomed to being screwed over in this career so they get as much as they can. It's not your place to try and figure all of that out.
