Update: I see a question like this was answered with an expected 2.5x gain over LTC. If so well then awesome! Anyway you can probably just ignore the original question, but I'll leave it in the post here.

Question on that scrypt-n mining. Specifically towards your scoring. They consistently have the highest scores. Like right this very moment Panda's score is 247.9 and VTC's is 224.2 which is significantly higher than anything else. Are these scores weighted against the fact that you only get about 30% to %40 of the hash rate (based on my extremely limited testing)? Or is that not a factor. I'm making assumptions on a scoring system I know nothing about so I know I might be way off base.
Regardless, I'm just going to point a couple of GPU's at it for a few days and see how it pays out and get the answer for myself, but I was curious.
