That picture is an old picture, and at the time stringing instructions would have been to strung bottom up where the mains finish at the throat.
Nowadays at Wimbledon we string ATW if the player requests 1 piece stringing and the mains finish at the throat.
The UKRSA is not a racquet stringing authority in the same vein as the USRSA, nor is it affiliated with it. It does not administer MRT certifications, nor professionally recognised certification.
