I am researching statistical characteristics of tennis matches. I need to know reliably which tennis matches are best of 3, and which ones are best of 5.
Is it strictly the case that only men grand slams are best of 5? Are the venues for the grand slams only used for grand slams (e.g. if I see that the venue of a tennis match is Wimbledon, am I guaranteed that this is the Wimbledon Grand slam)? Or are there sometimes some matches in these venues that are not part of the Grand slams?
