*Unstrung weight is part of the name given to this racquet by the manufacturer. String never weighs more than 25 grams, so if there is more than a 25 gram variance between Unstrung Weight and Strung Weight then the manufacturer most likely measured the Unstrung Weight of the raw graphite frame (i.e. without grip, grommets, or paint). In addition, due to the porous nature of graphite material, all manufacturers approve of a +/-10 gram variance during the manufacturing process.
