The
WTA doesn't keep official serve speed rankings of its own for all its events for a variety of reasons—mainly that serve speed isn't captured on every court at every tournament, and sometimes the technology being used isn't consistent from event to event. The Women's Tennis Association does have an external partner that it officially recognizes which measures and maintains serve speed data at selected number of events. It does not recognize at all, nor keep tabs of speed records set outside the main draw phase of WTA Tour tournaments. Therefore, serve speeds recorded from the qualifying phase of WTA tournaments are not added to the official WTA serve speed statistics. Also WTA tournament serve speeds recorded by different measurement systems or brands (at the discretion of the host or organizer) that are not using technology provided by ATP/WTA's official supplier or partner (currently SMT/IDS), or speeds recorded at any of the non-WTA professional women's tournaments such as the
ITF Women's Circuit, the
Fed Cup, and Olympics tennis are not added to WTA's official list of records. == See also ==
