I don't really care about methodology, as long as there is a reasonable, steady rate of advancement. One thing I introduced a long time ago, which the DM for my current group uses, is XP awards for things like writing a character background and writeups after each session. Of course, I'd probably do that anyway, because it is part of the fun for me in playing a character, but it is a nice thing to do and it also encourages others to do the same. I always enjoy reading other's writeups. I started it with Shadowrun (giving extra karma for it) as GM and I still have a notebook full of multiple writeups from each session for many different campaigns. They all make for a fun read even now, ten to fifteen years later.
