After a trial on gridding by average points (and subsequent discussion) during the rounds 2 to 4 of racing, we have updated the League Rules.
Rule 33 now reads:
All races will be gridded on the day by the Commissaire using average league points. Non-league riders, by prior request, with high national rankings may be brought forwards at the discretion of the commissaire. National Rankings may be used for a Category A event.
