I think you're crazy to not settle your capital where you spawn, especially if you don't settle on your first turn. There simply is not enough information available at the initial screen to determine whether you should settle your capital so many hexes over, and the starts will never be in such bad locations that you won't have access to some valuable resources early on.
Yeah, but sometimes it's worth to lose turn or two to get into better position. One missed turn can mean you'll end up on a hill and your city will be less prone to early aggression, and you can potentially grab one more lux\cow\wheat.
I wouldn't lose more then 2-3 turns tho, especially on higher difficulties.
