I am suspicious enough to think that it goes on...how often is anyone's guess.
But because of that I always take workout times with a healthy grain of salt...more important than the time (for me anyway) is the regularity of the works, it means more to me that the horse has been getting to the track on a regular basis than the horse having a bunch of fast (or slow) works, which may or may not be accurate.
