I'm afraid that you've already answered your question! Once dropping util doesn't really affect your scores any more, that's usually a sign that you're down to waiting it out. I'm assuming that you've already done all the clean-up that you can.
One semi-fun thing to do is to list all your accounts with their months and years of opening, plus any the months/ years of any baddies. Look for "birthdays": for new accounts, look for one month, 3 months, 6 months, 12 months, 18 months, and two years. For baddies, look for every time they turn a year older, plus the same first year mini-birthdays. List these out by month, and you might see some little hops as you hit these dates.
Fun, yes?
