I think they only need one cycle to do an evaluation. Normally you would go thru 4-5 of those a night. So, you don't get much sleep but they get what they need.
Hook up before going in? You go in about 8 or 9 at night and they spend a considerable amount of time prepping you. I think the afterglow would be long gone by sleep time, somewhere around midnight for those that are lucky.
Maybe they should provide an inflatable.
