Avery, Yes, this makes it much clearer. Looks like you have a tight humidity control system, which is a big factor (though I hope you are actually measuring humidity range to see if it works as advertised). The area I wonder about is "Standards." Looks like you have a lot that are not given much attention. Perhaps you are describing what you actually do, rather than what ought to be done. The revised formula has a much finer range of levels of service, which should help, but we should also be clear in filling in the numbers that we are trying to produce a recommendation, not a description of what we're doing. If you leave out the "Standards" factor, the formula gives you around 77 as the recommended workload - pretty reasonable given actual good humidity control. Plugging in the revised formula will probably put the recommendation will probably produce a result close to 70.
