Don't get fooled. I'm probably the only one. Ok, Igiski too I think, going by his picks. I use my power-differences, yes. But I'm adjusting them with injury updates, age developments, actual form and personal observation - plumbing it in manually for a change.
You think that's why my picks are so similar to yours? :)
Yeah, I do about 90% of my picks straight from my ratings. Though it's more helpful in some games than others.
