Phantom,
Technically you are right about Tie the knot winning more G1 races in Melb than Testa has won in Sydney but what i would have a closer look at is Tie the knot has contested 11 G1 races here, a quick rundown 2 Yallumbas 3rd & 2nd, 2 Cox Plates 9th & 2nd, 2 Mackinnons 8th & 5th, 1 Underwood 1st, 1 Caulfield cup 3rd, 1 Derby 2nd and 2 Melb Cups 6th & 14th, Testa in Sydney G1 races, 1 George Ryder 11th, not very good Testa, but you hardly had the chance to prove your self.
