Monster always will load two or four arms mainly..running all with full cycle is an operational nightmare and a pain in the ass.
We open arms as needed. If I can load one arm sweet, if I need a second, cool, after that I'll clear 1 bring the other arms down, load, lock, and check those, then clear cycle. After cycle bring the first arms down and repeat unload and load procedures, then go to the next.
Loading and unloading full arms can take about 7-15 minutes for a one minute cycle depending on guests and difficulty with restraints..so you'll actually eat up more of the line with four arm cycle, make guests happier, and not as much of an operational strain
