Horses and Disciplines

I'm working on these stats and everything, and I'm building a collection of bookmarked pages. One I can't seem to find is this:

How do you know which division is optimal for each breed? Is there a chart somewhere?

A horse's breed doesn't affect how well it does in its specialty. Only stats matter for that.

However, disciplines for certain horse breeds can be important for the market. If yiu want to sell a horse, its most likely to get bought if it has a discipline that matches the breed. Feel free to message me more about it. :)
