GaWC - Inventory of WORLD CITIES

I've just read a book by Jane Jacobs and she talked about Global Cities, and researching on the Internet I just found this website. I think it's quite interesting rating major cities from most global to less globalized. I think some cities are a little underrated, rating Shanghai only 4 points or Mumbai 3, and other are overrated (Brussels 8 points¡). I was surprised about founding Tashkent, Tijuana or Bologna as global cities (even with minimal evidence and 1 point). What u think?
