Actually there is also a note under the PEOPLE LATENT GAIN output 
variable.  (unknown page number but just after the input fields for 
People).  but it's not much more helpful and says "an internal procedure is 

The short answer (from looking at the code) is that the

TotalPeopleGain = Number of Occupants * Activity Level (activity level is 
input as an hourly schedule value)

Sensible People Gain is then a combination of internal coefficients applied 
to the activity level and the current mean air temperature in the zone

Finally, the Latent is Total - Sensible.

I will have to do a bit more work to get you the source and derivation of 
the internal coefficients.
