The best horse won on the day from a very average field [where the real talent was too young and inexperienced for the race] and we all saw history being made, but boy-o-boy lets not start comparing the Diva to Pharlap. 3 Melb. cups is awesome for that race [only] but the Cup is a canter for most of the race and then a 600m sprint and I forget the last time it was truly run. 3 Cox Plates would have been far more impressive.

Lets look at 'Might and Power' perhaps, due to similar start/win history ?

Might and Power 33: 15.7.1
23 group races for 11 wins
G1 starts 14 and won 7
G2 starts 6 and won 3
G3 starts 3 and won 1

Makybe Diva 36: 15.4.3
25 group starts for 11 wins
G1 starts 14 for 8 wins
G2 starts 9 for for 3 wins
G3 starts 2 for nil wins

Lets not get carried away or even start mentioning Pharlap [or a heap of other greats]

Pharlap only won 1 Melb. Cup, so what ?
