Points in the Sprint and Middle/long columns are the sum of the ranking scores for the top 10 athletes for the corresponding federation. The Federation League points (last column to the right) are calculated by adding the Sprint points to two times the Middle/Long points.
Two Federation leagues for MTBO (Men and Women), where best 5 athletes count as the sum of all points .
Two Federation leagues for SkiO (Men and Women) where best 5 athletes count as the sum of all points .
One Federation league for TrailO where best 5 counts. Since the TrailO score is opposite the other disciplines we need another calculation. The best TrailO athletes have low score and it works fine to sum up top 5 to get a new score and the best ranked federation have the lowest score. However, if a federation have less than 5 ranked athletes we need to compensate for this by adding 90 points for each missing athlete.
