It's debateable how accurate this information is; however, the billions of meters corresponds to a lens with focus set at infinity, and I wonder if the 0.0 indicates you were at the near limit of the lens? Or perhaps closeup work under 1m?
The critical information which you've omitted in your post is whether the EXIF data corresponds to your observed shooting distance.
In some shorter range work, at least, the EXIF seems fairly accurate.
