That sounds broadly similar to B5's way of hyperspace navigation. Of course clouds don't have gravitational inclines, nor do they randomly twist, bunch or warps space. Plus of course even if you get lost in a cloud, you can usually find the ground, one way or another. Get lost in hyperspace, you'll be lucky if you're found within the next million years. 
In short, I don't think dead reckoning would work in hyperspace.

		 Ira Steven Behr (played by Scott Bakula) is written with all the subtlety of a man that stole all his ideas from JMS, that is to say that he's played as a loon that tries to blow up the station because he's a loon. He fails, he gets punched upside the head a few times, and life on the station slowly goes back to normal. Except now we have computer scientist monks.
