I'd say a lot more than half the time. Since I usually lose my stab to an act of supreme lameness, such as a HO or a lateral shot when fighting someone else, I mostly try to deny the the kill in those cases. It's become a sort of hobby of mine. Will look later and see if I have any on film.
Like Karnak eludes to you have no control over your yaw, the trick is to keep your nose pointed slightly below the horizon (mostly) and stay fast enough for a flair at the end. Don't be alarmed by your airspeed indicator, you are often going sideways or even slightly backwards here and there.
Strange topic. Filth described the analogy very well.
