I think you are using common core math.
My family refuses to go see the horror of an "attraction" that Stitch has become. The biggest claim to fame for the laugh factory is that is isn't as bad as Stitch. My math shows that as plus 1 E-ticket minus...well minus not much at all.
In all seriousness, I think WDW should be ashamed of the Stitch ride. When I saw the poll my first thought was that there had better be a choice that got rid of Stitch.
