Numbers can change the way something is looked at. A title might seem interesting because of its artwork or the way it is presented, but once a figure is placed beside it, the impression becomes a little more grounded. There is suddenly something concrete to pay attention to instead of relying entirely on what looks appealing on the screen. That is particularly useful with slot information because visual presentation can only tell you so much. Two titles can have completely different themes and still leave you with very little measurable information at first glance. A percentage such as RTP gives another point of reference, allowing the numbers to become part of the research rather than leaving the decision entirely to presentation. https://rtphi.com/
