10. Welllll, I think it is a bit easier to change than a habit. I mean, to bring up a series where similar wank occurs: when I first read TRC, the only spelling of Fay's name I knew was "Fai," because the character book wasn't out yet. I spelled it that way for almost a year. When the book finally did come out, I switched to the official spelling with very little trouble. It didn't really take that long to get used to it. I suppose the difficulty varies from person to person, but I always get confused when people say it's just too hard for them to change.
