Wheel of Fortune

On Wheel of Fortune, what percentage of the time does the person who spins the wheel first manage to keep control all the way through and solve the puzzle?  No “Lose a Turn,” no “Bankrupt” no incorrect guesses.  Just straight through.  I'm wondering if it's always an advantage to be the first person spinning?

That could be a nice bit of data-crunching journalism for a site like FiveThirtyEight.com.  And then all the bored people in office buildings could read the article during their lunch breaks and be like: "Huh.  Never thought about that.”
