Oh for sure, I had 2 prior tournaments before working up to the 1700. And in one I finished 3rd place (in my division) and even got a very small trophy, lol. But the rating was still "provisional" as I did not yet have enough experience/games to earn an official rating.
And this was a while ago (early 90s). I'm not sure how things are done now, or if FIDE tournaments/ratings are similar to USCF.
One thing I remember is how the kids I played against seemingly memorized opening sequences flawlessly. In between matches the participants were all set up with roll-up vinyl boards on picnic tables just drilling each other on openings from the MCO book. I didn't realize how important rote memorization was at the tournament level. It was like actual strategy didn't start until move 10 or so for some of these players.
