Basically - what you suggested might be happening, isn't ballistically possible.
To get a 40fps difference downrange and still hit the same aim point, you'll be starting off with a 60fps difference at the muzzle, so you're taking sand out instead of adding it. (I think).
Anyhoo... it's not really important and probably just adds confusion to the thread to dwell on it too much. My opinion is it's probably erroneous data.
