gurgus estimated 100% on 2017-11-22
Bruno Parga estimated 70% and said “Nadal is at 15/8 and Djokovic is at 7/2 in the betting markets. Even if you disregard all other players, 100% still ignores the chance that they get injured, involved in a plane crash, banned for doping, accused of sexual assault, defenestrated…” on 2017-11-24
gurgus judged this prediction right on 2018-11-20.
