The instructions are executable to direct one or more processors to access reference gaming deployment data based on an electronic communication with a processor that is associated with a gaming environment. The reference gaming deployment data is related to one or more gaming units that have been operated in the gaming environment during a first period of time. The one or more gaining units correspond to a reference gaming deployment in the gaming environment during the first period. Also, the instructions are executable to direct the one or more processors to access changed gaming deployment data based on the electronic communication with the processor. The changed gaming deployment data is related to a change to the reference gaming deployment that has resulted in a changed gaming deployment that was implemented during a second period of time after the first period.
