3.7.1 If the opponent pulls closed guard and remains suspended in the air, the athlete will have to put the opponent’s back on the ground within 3 (three) seconds and stabilize the top position for 3 (three) seconds to be awarded with Takedown points. http://ibjjf.org/wp-content/uploads/2014/05/20140507_RuleBookIBJJF_v3.pdf Finally, guard jumpers are going to lose 2 points if they get return on the ground within 3 seconds. Guard jumping is only applicable for sport BJJ and is now discouraged by the loss of 2 points. Time to learn how to throw or pull guard (drag the person to ground) instead of hugging  like koala on a tree. Also, lot of injuries from jumping guard as well will be prevented.
