With DD#1 I was scheduled for an induction at 41 weeks and 6 days, but I begged and pleaded to get an extra day. (Un)Fortunately, the hospital didn't have any room for that extra day at 42 weeks and 0 days, so I was scheduled at 42 weeks and 1 day. And guess what?! My DD#1 came naturally on 42 weeks and 0 days without an induction. The point is every day counts! You might not even have to go that long to the induction, maybe something will happen before then. And with the PP's question, why not go to 42 weeks, why 41.5 weeks?
Having said that, most people in this forum prefer natural versus induction (including myself!) but I know plenty of people who induced who had successful, "average" speed labors. Don't fear an induction just because it's not natural -- you can still do things to ready your body (evening primrose oil, raspberry redleaf tea, walking, etc). Do whatever you think is right for you.
