yeah, i would like think you can breed a curve profile with another curve profile and get a somewhat expected outcome (if you did it 100 times a pattern would emerge), but you can't do that really. Mares can birf 2 per month. I think top players probably got to beta the breeding and run some sims.
remember that horse that someone linked where it had the worst curve. almost totally J-shaped. https://knowyourhorses.com/horses/7042
You can kinda see how that curve was formed. This is only the bottom of the chart lol. Anyway, this poor bastard has some good original blood from https://knowyourhorses.com/horses/6682 a good Z10 Buterin Gen
i wish more of the horses had longer race histories, but if you squint you can sorta see a pattern emerge. But, if you had an idea about how to shape curves over generations of horses, you could turn all this 'trash' that is being sold right now into something. It's kinda why i might start looking to snap up cheap genesis fillys just to have more breeding stock to play around with.
But agree, when breeding starts, market is going to flooded with horses. I think that will be the time to snag some Legendary Nakamotos to add some fancy horse to the stables.
