Consider evaluating if the MATERIALIZED keyword is necessary for the filtered_challenges CTE. While it can improve performance by caching the result, it may also increase memory usage. Ensure this trade-off is beneficial for your use case.

The MATERIALIZED keyword is used for the registrants CTE. Verify if materializing this CTE provides a significant performance benefit, as it can increase memory usage. Consider removing it if the performance gain is negligible.

The LEFT JOIN LATERAL for winnerHandle and registrantFinalScore could potentially be optimized if these subqueries are expensive. Consider evaluating their performance impact, especially if the dataset is large.
