The RR Score is not yet a precise figure. It summarizes the data we have today (specs and reviews) and changes as more information comes in. A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy.
