        1. A Time Control of G/M dN means each player gets M minutes/game and a delay of N seconds/move (before the clock starts ticking). A Time Control of G/M +N means each player gets M minutes/game and an additional (increment) N seconds for every move.
        2. We place players in groups or sections based on their USChess rating supplement.
        3. A group may have 3-7 players if the number of players is indivisible by 4 or 6.
        4. Some Swiss sections may be merged because we organize more smaller tournaments during post-COVID times. Unrated players are placed in under 500 sections by default.
        5. Rising Stars event introduces in-person tournaments to new players and their parents (who attend for free). A player may attend only one Rising Star Event (during which they play 3 games).
        6. Our answer to inflation is to have rock-bottom 20th-century prices! The only thing is that we can't offer BA€oins (nor prizes) at this fee.
        Note: We use AzhLangareted Cadence in these tournaments to optimize the parents' (and players') time; each round (of games) starts about 5 minutes after all games in the previous round end.
