Answers.Text: Weeeelllllll......Ratings are not recalculated every round, but the effective rating of the player you're playing changes every round, as the previous round results play into the calculation made after the tournament is submitted. Remember, there's absolutely no guarantee the player you're playing will play another round in the event.

Answers.Body: <p>Due to the huge upsurge in rated players, and the lesser skill level required to become one, we see a player becoming rated every other day. If USCF did not implement this imbalance, Fabiano Caruana might get rated at 3000+ as rating is being 'added' into the system for every new rated. This imbalance 'subtracts' rating from the system to keep it more or less even.</p>

Answers.Text: Simply having more players doesn't create inflation. And there is no such imbalance; if two players with the same rating and same K play each other, the loss will equal the gain.

  It seems that when one loses a game against a compatibly rated opponent, the (USCF) rating point decrease is more significant than when one scores a win.
  
  For example, between two 'C' players, losing an over-the-board game may cost a player 12 points, whereas wining, the increase in rating is 7 points.
  
  This is an odd phenomenon in the Elo system. Is there an explanation?

  How much rating you lose or gain depend (besides your and your opponents rating) on the [K-factor](https://en.wikipedia.org/wiki/Elo_rating_system#The_K-factor_used_by_the_USCF). If your opponent has a different K-factor than you do, the gain/loss of rating can be asymmetrical.
  
  In the Fide Elo system the K-factor depends on rating and age. Apparently the USCF has a K-factor that is dependent on the number of games played overall and in the current tournament.
  
  So, that is probably the reason for the discrepancies you noticed. But it has nothing to do with asymmetry between winning and losing.
