I was wondering if there was any way that your year's worth of premium only counted for the time that you actually had more than 4 games.
Say for 3 (or however long) weeks out of your premium year you are on vacation or unable to play many games at all. Would it be possible to have any time you only have up to 4 games not count for your premium time?
This might be way too complicated for lack to figure out, but I think it's worth a try!
