In the Winners Section the letter codes refer to the Losers Section stage in which the (losing) player enters. In the Losers Section the letter codes reference to the Winners Section (helpful to understand sudden appearances of new players in several rounds of this section).

The first eight players who lose two games drop out of the Challenger tournament. These players thus are the losers of the 1st and 2nd round in the losers section. The players who drop out like this can of course re-enter the next edition of the challenger tournament by normal means.
