I read in an espn article that Tennis federation measures all atp and wta courts speeds and categorizes them 1 to 5 (1 being slowest and 5 being fastest). Does anyone know how to find this info? For example if i want to find the rating for upcoming ATP dubai champion shiops or the acapulco tournament, where do i check the court speed. Also, each tournament has more than 1 court....are all the courts same speed for a tournament or each court can vary in speed? Anyone know the rules on this? thanks
