How does DUPR prevent tournament bracket sandbagging?

Tournament directors use DUPR rating minimum thresholds and dynamic bracket locking to prevent 4.0 players from registering in 3.0 brackets.

The detail

Historically, tournament players intentionally self-rated lower to win medals ('sandbagging'). DUPR's automated tournament integration automatically blocks players whose verified rating exceeds the bracket ceiling (e.g. A 3.65 player cannot enter a 3.5 max bracket), ensuring competitive fairness.
