I think it's better to repeatedly hit j rather than count "ah, 5 lines" and type 5j. Even better, you're already looking at where you want to go, it may be faster to hit / and start typing from that point to jump there.
Or, and this is a wild one, grab the mouse and click the point where you want the cursor, rather than giving some sort of treasure map to Vim: "Starting at the typedef, take 5 steps right, then 10 steps down, and 2 more steps right"
