Random question or total amazement or despair idk!

So randomly I have noticed that within the Andalusian breed there are a lot of mega stat (like over 6k) horses with over 90s confo & Excellent individual traits & I was just wondering how on earth do you even get those kind of stats/confo?! 

How long would it even it take?! I could play this game for the next 20years and not even come close! 

*slopes off to glare at not very good ponies in the hope they might get the hint & improve themselves*

From what I see the majority is from veeery very long lines - it's at least 16 generations involved, if not more. The high stat horses changed hands, offered outside breedings and so, the ancestors of the horse belong to more than one person. Don't worry though - the stats of the foals usually grow quicker with every next generation, so with careful selection you'll need less generations to leap from 1000 stats to 2000 than from 100 to 1000+.
(someone please correct me if I'm wrong)
