Well the percentage of people that won compared to the number of DIS winners, it is very high. Right now, if no new people won, essentially 25% of the winners were from this board. But, thinking about it, it kind of makes sense: this contest isn't very well known, and isn't advertised very much, especially not towards the end of the contest. And because the contest is sort of hard to find on the Disney website right now, only people that know about it ahead of time, aka DISers, will really enter, and really only people that visit these boards often, like most of us do, will remember to keep entering it. Obviously not just DIS people are entering, but the contest has kind of ended up being tailored towards DISers...
Those are my thoughts on the contest at least.
