While that's all very good ... for getting you a nice table on KM night, the fact of the matter is the KM fields would be no different, the party would be no different, the amount of posers out in force would be no different, the hyperbole and hoopla would be no different and probably even the prices paid at the sales would be no different if both of those races were run for $500k!
As for your claims regarding race days and clubs inputs you show a complete misunderstanding for how it all actually works, this KM day is gifted to the ARC by those that run NZracing , NZTR in its wisdom seldom strays from its approach in appeasing those that run NZracing (see Stakes distribution, clubs in line for closure via assistance (most of it underhanded I might add) from NZTR amongst others , free PR etc etc for further examples) and thus bow and scrape to their beck and call.
