I wasn't going to mention it but the prizemoney is $100,000. Lowest on the grand circuit is $ 250,000.
Did the crowds fill up, was the betting ring full? Anyway those things can happen at country meets so irrelevant.
The placegetters do diminish the value. The Grand Circuit is about the best of the best all coming together to battle to see who is the best of the absolute stars of the sport, not 1 or 2 of the best coming together. The winner of the Miracle Mile, ID, Vic Cup, NZ Cup etc all beat a way superior field to that of the SA Cup, Tas Cup, Truer Memorial so its only fair the winners of those superior races get special mention as grand circuit winners. The SA Cup is still a Gp1 so I don't really see an issue.
