How Fide rapid/blitz rating calculation is done for the first time?

Hi,

This one is my very first post in chess.com & actually i am a bit confused about one thing.I dnt have a fide standard rating so far. but last week i took part in a rapid rating tournament.No player had a rapid rating before this tournament but many of them had a standard rating. the seedings & pairings were actually done on the basis of their standard rating.It was a swiss league 10 round tournament. I scored 3.5 points againt rated(standard of course) players out of 9 matches. Scored a total of 4.5 points. according to chess results server,i had a performance rating of 1471.If i calculate the standard rules of getting first ever rating,then i have something like 1550. My question is how this rating will be calculated for the first time? & most importantly,will i get a rapid rating before having any standard rating? please help me regarding this matter.Thnks for reading the post.
