It really isn't that difficult to figure out if someone is a good player or not. While it is true that none of the systems currently in effect are perfect, when they are all viewed side by side one can get a good indication of another players skill. For example, Cockney, you have 1222

and a 60% win/draw ratio. Your ghostrating is currently 78 and your all time gr is 147. This tells me you've played against some good players and won games against decent competition. You're win/draw percentage is excellent so everything combined, I'd come to the conclusion you are a good player, and would probably be fun to play with. This is not something difficult to do and I don't see where the problem in figuring this out comes from. In tournaments I would think that having several criteria would solve any problem of competency.
Ex. To join this tournament you must have a (GR over 200+a W/D of 55%) or (GR over 100 + a W/D of 45%) or (750

total plus a GR over 250 and a W/D ratio of 60%)
I'd say something like that would cover pretty much any decent player and exclude any dumb ass competition that's managed to gain either a lot of points by playing all noobs or anyone who just got lucky in 1 game against a lot of pros. Feel free to alter the #'s as you see fit. I see no need for a new type of rating system. And yes I realize that some people are anti-gunboat and anti-ppsc but both of those versions require skill.
