Update: I was unfortunately not aware of Shamus Young's severe criticism of Fallout 3 available here to link in the original piece and I regret that. It dovetails rather nicely with what I've written and it's much better executed than my piece. I strongly recommend anyone...
Don't twitch to correct your trajectory it's ok hitting obstacles.
You don't have to go through the rings so don't force yourself to do it.
Learn the patterns the obstacles arrive in and be ready for what's coming next.
