I don't see how it could help, since everyone has the same score band. I got a 171, so my band is 168-174, right? It's +/- 3? So they could look at me and think I'm capable of a 174, but that's true of every person who got a 171. And if you compare me to someone who actually scored a 174, then that person is capable of a 177 in the same way that I'm capable of a 174. I think they're pretty much useless.
