Classes may be used to produce different certificates for different groups or 'classes' of entrant. Class can be assigned manually, as in the RBLR1000 to distinguish route for example, or can be assigned automatically using entrant scores, bonuses visited and/or rank.
Class 0 is the default class for all entrants and may not have any filters applied. Other classes are examined in numeric order starting at 1 until the filter criteria are matched. If no matching class is found, 0 is applied.
