Why would you break it up....just keep moving until you get out.
If it has structure and some degree of the participants doing things correctly then by all means. IME though, in Aikido, many don't have a clue what to do at this phase and it becomes a brawl with no purpose.
I'm an advocate of the full spectrum of rqndori and of training jiu jitsu throughout the entite spectrum. Problem is that very few people or schools do this.
No worries, just pointing out why I feel that many schools don't do more randori. It is hard to keep it confined to the one spectrum or area you train on.
