The point is it's highly variable. As stated in the first comment: whether it's worth the time and effort is up to you.

I'd argue that 1 year is way too short. The lack of patience causes far more problems today than building up the relationships and gaining the network and momentum to get into higher positions. Most people I know who stuck to a clear goal within a organization that has openings have done better than those who kept jumping around looking for the quick rise.
