What GoPro means by 'wide,' 'medium,' and 'narrow'

Here are the 35mm equivalents, straight from the horse's mouth:
Wide: 14mm
Medium: 21mm
Narrow: 28mm
     The equivalency listed above is between GoPro's nomenclature and actual focal lengths of wide-angle lenses for 35mm film cameras or full frame DSLRs. A normal field of view (FOV), approximating that of a human eye, would be produced by a 50mm lens in such cameras.
     What GoPro calls "narrow" is only so, relative to other GoPro FOVs; in conventional terms it would be considered a moderately wide-angle FOV, which would include 35mm film camera lenses up to 35mm in focal length.
