Set:
• Score Weight — weight per challenge (0–10).
• Number of challenges to be scored — The highest scores will be added to the final score.

Example:
Selectable set with 3 challenges, Weight = 1, Required = 2
→ The two highest-scoring challenges are used, so the total weight for this set is 2 (1 × 2).
Note: You can create up to 10 challenge sets in total (across Required, Selectable, and Random).
