I have never said that.
That is good to know. I am trying to figure out what you're even getting at with this issue.
Is it your hypothesis that hard courts (let us pick the AO and the USO as examples) have not gotten slower over the years (defined in a way that is independent of what racquets or balls are used), but that the new racquets/strings have made them appear that way?
