In order to be included in the official Ranking for an individual test, a competitor's achievement must be verified at least twice during the 10 tries. Only verifying that a record was obtained once, however, will still add the corresponding points for that record to the competitor's total accumulated points. Competitors may not be included in the Ranking for records obtained during the final try in any given test.
As an exception to the above, should a competitor break a World Record, said competitor must immediately demonstrate his ability to memorize the same number of digits in order to confirm this record. In this sense, it will only be considered a world record if the competitor can repeat this feat in the extra try or, as in the case of confirming records to be included in the ranking, during one of said competitor's remaining tries.
World Championships
World Championships will be held every other year, coinciding with years containing uneven numbers. The fastest memorizers in the world may participate in World Championships following classification.
First day: Finals for all categories except the Open category. Semi-finals for the Open category. That competition will determine which aspiring competitor will go on to the final round.
Second day: Final. The aspiring competitor will challenge the World Champion.
