because they are trying to do different stuff... personally i'm not liking it that much, the houffalise race was too techy, the next one too open... the worlds too townie... but they are trying.
persoanlly if they want to add events, a time trial of the XC course, or do this eliminator as 1 lap of the xc course. Or even better, say to win you have to do both the DH and the XC TT on the same bike, combine points to win.
