-Please note that there can be significant variation in the average difficulty of questions within a single category, and, therefore, directly comparing statistics may be misleading.

-In order to be eligible to be ranked in a given category, a competitor must have correctly solved at least two questions in that category. Competitors must have speed scores under 120s to be listed.

-The below stats reflect the individual’s season mean in each category. Please note that the overall speed/score used in the standings remains the individual’s median score. Additionally, the “average score” for each section is the median competitor’s average score.
