So you are not placing any weight on the UK / European racing jurisdictions having higher quality of race standards from 1600 - 3200? They breed their horses for middle distances and higher whereas Australia breed for pure speed mainly.
How many times do you see C grader UK horses come to Australia and dominate let alone their B graders. It's not a criticism on Winx but lets be frank, the racing over her distances in UK is hellva lot stronger than here.
Look at a horse like Benbatl, a nice little horse with a handy record who came all the way out here after travelling the globe and put up a great effort against Winx at her absolute peak at her home track MV which is a tough track for a UK or newbie horse on it. Now Benbatl being the handy little horse that he was doesn't even rate a mention for "LONGINES WORLD’S BEST RACEHORSE RANKINGS TOP 50".
Cracksman, Enable, Gun runner etc are champion horses in Europe and Benbatl doesn't rate within 6 lens of them. Winx only beat him by 2lens after having a slightly easier run on her home track and at her peak race start - GF
