With an adjustable cup and cone hub there is no reason that you should wait nor any reason that the hub shouldn't be properly adjusted from the factory. You seem to be working under the idea that the hubs need some kind of "break in period" but they really don't.
I'm not sure why Shimano over tightens their hubs but it seems to be a consistent issue.
