Tournament Spreads

Is there a 300 point spread in OTB chess tourneys?  If so, I'll shut up but I just witnessed about a dozen players, myself included, leave a chess tourney because there's no way we can compete with someone who is 300 points better.  A 100 or 200 maybe but 300, forget it.  Now, I will play better who are better in the hopes of learning but when I only have three tourneys a day, I am limited.  It's frustrating seeing that I am ranked 3rd and everyone is within 50 to a 100 points 30 minutes before a game I have to drop out because of stronger players.  Yes, I am getting better.  No, it's not as fast as I would like.   But in the meantime, I am wondering about the spreads for online games.
