It's not really an arbitrary number in my mind. Each season, before it ends and after rollover, I send a sitemail to each owner in jeopardy. It has a number attached to it that falls within the 55/125/195/280 guidelines. Sent to Coop owners a few days ago;

New guys, you must win 55 in your first season.
Good luck to all

As you can see, there are no arbitrary numbers. If you'd like, I'll show you the one sent last season if you want to check trades.
