I think it's a good thing that they're factoring in some sort of outcome measure. I didn't read the entire methodology section in detail but I know they used Payscale as one of their sources. There's no doubt that Berkeley is one of the world's best schools. I have no objection to the #1 ranking. I'd like to know more about the outcome measures because I suspect that it's a slippery thing to quantify.
