Discrepancy between PIform3 and WE P1 re: Occupancy

These discrepancies are part of the reason there is so much confusion about calculating FTEs, as you can see from the posts here. The Glossary of the reference guide attempts to define FTEs, but does it in a vague way that doesn't clearly indicate whether retail customers are in or out. WEP1 indicates that retail customers are in the FTE calculation, rather clearly. CS Appendix 1 quite clearly separates "employees" from "Transients", yet does not address what types of people are in what category. CS Appendix 1 seems to assume that retail customers are not part of the FTE calculation, adding more confusion. This reference http://succeedatleed.com/2009/12/make-calculating-ftes-less-confusing/ seems to indicate that the proper way of doing this is to count retail customers only as transients, and only count employees as FTEs.

Meanwhile, on the PIf3 template, we are asked for "peak occupants" which is not defined in the reference guide nor int the template, but unhelpfully has the caveat "does not include residents". One can assume this might mean only employees, but that is not stated explicitly anywhere in the template nor the reference guide. "Peak occupants" is not defined in CS Appendix 1, nor in the explanatory text under WEp1 int he reference guide nor in the glossary. This inconsistent use of terminology, vague and conflicting definitions, and lack of a clear method is one of the reasons we see so many questions about this topic.

"Peak Occupants" on the template includes exactly whom? Only employees?
