Yup, I have seen 100% constantly also. I have never done a factory reset between updates, since I assume I would have to enter a ton of stuff again. It would be nice if the save file was editable (is it?), so you could at least keep some main settings, while avoiding possibly loading some bad past settings.
I have also noticed my upload speed is limited to less than 1M, but if I go around the router it is 5-10M. I never know if I should post stuff like this, since maybe it is just the way it works or is due to never doing a clean install.
