I have always been confused by the stats system that is used to rate table tennis rackets. Some companies use a three dimensional scale as: "speed", "control", "spin"; while other companies use other stats as well such as "stiffness", "hardness" and "consistency".
What's more confusing is that while the higher number is usually "better" cheaper rackets could be pretty much in the same range as the extremely expensive rackets. Is it so that the rackets are rated in price categories or how does the rating system work really?
