Discrepancy in Peak occupancy and daily average

We have received the review report from the assessor for our office project. It has been stated that- ''The daily average value should typically be higher than the peak value.'' This statement does not seem to hold true technically as far as the definition of the two types of occupancy is concerned. Do you think it is a typo error OR am I not clear on the concept yet? Please explain. Also, if I have the following pattern, how can I calculate the daily average and peak occupancy as the two shifts overlap? A. 115 occupants - 9AM - 6PM B. 12 occupants - 2PM - 10PM C. 12 occupants - 10PM - 6AM Thanks!

These definitions confuse a lot of people! The daily average number is the total number of people who will come to the building on a typical, average day. In your case it looks like your daily average is 115 + 12 + 12 = 139. Your peak is 115 + 12 = 127 during the shift overlap from 2pm to 6 pm, the busiest time of the day. Does that make sense?

Thanks David! But, on the PIf 3 form, the daily average is mentioned as the sum of FTE and transient occupancy. I am sorry but I forgot to add the transient occupancy which is '3' between 9AM - 6 PM . In which case, shouldn't my daily average be = (115*9)/8(FTE for first shift) + 12 + 12 + 3(transient occup.) = 157 ..? Also, the peak would be in this case, 127 + 3 = 130. Right? Look forward to your response.
