B&m coasters are made for capacity especially the hypers. You just have a clambshell restraint to give a quick check, no seatbelt, and you dknt have to bend over as low like on other coasters. Other parks has a 60second clock in the station. Ours would have to be 180 seconds.
It would take no time for two people to run down one side checking 16 restraints each, but they have 6-8 crew members checking restraints.
