When registration is low, combining divisions can help ensure players get the matches they signed up for. But the right combination requires more than finding brackets with similar numbers.
Evaluate skill level, age, and how those differences may affect the playing experience. An age gap that seems small on paper can have a meaningful impact, particularly among older age groups. Consider the specific players involved, the competitiveness of potential matchups, and whether another grouping would provide a better experience.
Remember, there may not be a perfect solution, and not every player will agree with the decision. Weigh the available options, make an informed decision you can explain and support, and communicate changes to affected players as early as possible. A clear rationale helps players understand the decision, even when it isn’t their preferred outcome.
