Well I didn't actually look too much into the GMTK jam, since I was sort of bummed about my own performance back then.
But a thing I can say for sure is that triple the number of raters helps for sure. More good eggs outweigh the bad apples.
Makes sense. I also think that the 48h dev period scares off the total n00bs. And this is a bit of speculation but the GMTK seems to have a little bit difference in the target audience. But that's a lot of conjecture.
