I worked hard to reach over 8500 but now I'm stuck on about 7600, it's so frustrating, I can play for an hour, winning or coming 2nd each race and get back to 8000 but all that work can be cancelled out by 1 random disconnection!! Last night for example: I started on about 7500 and got up to 7900, came first in a 12 player race and then suddenly the "disconnected from other players" message appeared. It not only stripped me of my last win, but stole 250 or so points from me! So back to square one again. This has happened time after time. It takes a long time to rebuild the points again, with the ongoing fear of another DC. I hope nintendo can optimise how they handle client disconnections better. It is probably designed this way to prevent people from "pulling the plug" when their losing, but to penalise us when it's not even deliberate is harsh.
