Rule #5 - You can only challenge once per month for the title. If you lose you will have to wait till the month before issuing another challenge. Also, because of rule #4 if you were ranked 2nd and lost to the champion, you will have to wait till the the guys ranked
3rd-6th get a shot in that month, that is if you are still ranked in the top 6 after losing, if not you have to fight your way back up before challenging for the title. Also, because of the wait you may not be able to challenge for the title for more than a month, this puts added pressure on each competitor to be at their best every week.
