Thus, with 7.52 hours of workload during the 12:00 a.m. hour, 12.5 police officers are required to meet that workload while maintaining the 60 percent saturation threshold (7.52/.60 = 12.5). The same calculation is made for each hour of the 24-hour period and the result is the number of police officers that are required to be available to meet peak workload and maintain the 60 percent saturation threshold. We then have to go one step further. Staffing patrol coverage is a challenging task. In order to have a certain number of officers available during any given hour, additional officers must be assigned. Training, sick time, court, vacations, and a myriad of other responsibilities take 19
