It\'s far from an exact science due to the varying sizes of the horses and their unknown weight carrying ability (some smaller horses are better weight carriers than larger), but I\'ve always believed there is a real maturity edge between 3 and older (looking back at the record, such as Slew losing to the older Affirmed, and Slew beating the younger Bid, etc). I handicap as such, and believed that Songbird would likely lose this race due to competitors of similar talent being in there who held that age advantage. I almost lost that bet (wow, what a race).
