We try to be fair by using a unique, mathematically sound Weighted Rating algorithm. This proprietary rating method continuously recalculates the Rating shown with each Software Title. The algorithm accounts for both the Number of Reviews, and the individual Rating Score provided by people like you. Finally, the resulting Weighted Rating Score is scaled to fit the range from 0 to 5 so you can see where the POS Software ranks in comparison to the other Software Titles registered with POSSoftwareReview.
