I have a provisional FIDE rating of 1980 based on my score of 1 (two draws) out of 4 at a FIDE-rated tournament earlier this year; see: http://ratings.fide.com/card.phtml?event=2059100 where provisional rating is Rp. I am playing in another FIDE-rated tournament next weekend and I seem to recall it may take as few as 9 games against FIDE-rated opponents to obtain an official (non provisional) rating, though I'm having a hard time authenticating this.
This is important to me as it's a 5-round tournament coming up and I want to know whether taking a bye may mean I have to play in yet another FIDE-rated tournament after this one to reach the plateau of 9, if that is indeed the correct figure.
