ASHRAE Standard 90.1 Table G3.2 and occupancy sensors

Hi everybody, My team and I are working on a CI project (office floor) where the tenant has installed occupancy sensors for up to 75% of connected lighting load. In that sense, I would appreciate if someone would tell me if that means that we get the 15% reduction in lighting power as shown in Table G3.2. (Yes, the office floor is less than 1500 ft2) If not, how much reduction in lighting power do we get? and how do we perform such calculation? In other words, what is the correlation among the amount of sensors that are in place and the percentage of reduction in lighting power?
