Duritz, you said:
a)"What I mean is, it took a little bit of insight to say MD will love the extra 400m."

How much insight did it take? Not a lot. Everybody and his dog was on MD (apart from super optimists who still think a Sydney donkey could beat anything from Melbourne) and there have been 4 off the cuff examples of the simplest sytems that would pick MD.

b)"If RoboAnalyst looked at MD he'd say "Beep Beep, she won G1 Australia Cup over 2000m, beep beep, she is at her best therefore at 2000m, toot.""

Have to disagree again. Even on a bad day in boxers and lubricated with vodka RoboAnalyst would say that MD was best at 3200, better than GA at 2400 and almost as good as GA at 2000, depending on how he was programmed of course.
