I also agree the %'s are totally off. For me i found that certain numbers are better than others like, 76% chance yeilds better results for me than 85% chance for some reason. 85% chance for me means i'll miss atleast one pick per node. But 76% i rarely miss. And it's not even just those numbers. 72% is horrible for me as well, but 69% gets better successful picks. 92% is also a horrible number but 88% is good. So i'm really not sure how their system works.
