3. Does the age of a runner's dam make any difference to its chances of winning?

While following racing you will hear various biases expressed relating to the age of dams and their ability to produce competitive racehorses. These usually take the form of doubting the ability of first foals or the products of old dams being less competitive. The table below shows the wins-runs by different foal numbers relating to 2yo racing in the 2004-6 seasons.

It would be interesting to extend this table to take account of class of runner by foal number. For example, although older dams can produce competitive 2yos, are they at a lower level, on average, than the product of younger dams?
