I am not sure why it says on the documentation screen shot that the total occupancy for the VRP calcs should be consistent with occupancy for other credits. For example we have 1,100 full time occupants, but the occupancy for the VRP will be higher because it includes occupancy of rooms such a conference rooms, etc. Where as you might have an occupancy of 79 in a conference room, but there won't actually be 79 people in there at all times.

Hi Nena
For multi-zone systems, the total population serving that system and the additive of all systems should equal the amount listed in other credits. But then the critical zones, such as a conference room, will have more detail into the peak population of that individual zone. The VRP calcs will take into account both of these variables.
And generally speaking, if you have a higher population than your other credits, you are actually under-accounting for outside air delivery. So if you're using this approach and still meeting the prerequisite requirements, I'd just be sure to note that you are aware of this discrepancy in some sort of narrative as supporting documentation.
Thanks!
