The racquet appears to be a Babolat (Roddick??), so it can't be that old. And you can see the starting clamp near the throat, so it is obviously a two piece job.
I would imagine that the UKRSA is following the lead of the USRSA in terms of stringing guidelines. If I took their Certification test and strung that way, I doubt they would give me full marks.
I just think it's odd that a Racquet Stringing Authority would post a picture of an improperly strung racquet....or at least a racquet that doesn't follow the recommended guidelines for stringing a racquet.
