This thread could open a discussion about the changes in both, number of events and quickness of the surfaces.Letīs pick 1980īs and 2000īs.
Number of Events
Clay and grass keep more or less the same weight on the tour.But Hard is the official ATP current surface while it was indoors in the 80īs.it wouldnīt surprise me if there are so much hc events now as indoors back then and, also, as few indoor events now as hc events in the 80īs
Clay and hard have, more or less, similarly.maybe current hard is a little slower and current clay is a little faster but, on the long term, it doesnīt make a big difference to me.
The real differences are on grass and indoors.Nothing to see at all.Speed is absolutely changed.
