I’ve said this elsewhere, but while the purpose of the extra day was to avoid more frequent late night finishes by instead having a minimum of two matches in the RLA day session, it is still inevitable there’ll be at least one or two days that’ll result in a post-midnight finish.
FWIW, Novak Djokovic has only ever lost in the first round of a Major tournament just twice, both at the Australian Open (2005 and 2006). The former was at his first ever Major, where he faced and lost to the eventual champion, Marat Safin (who of course beat Lleyton Hewitt in the final).
