just spent a few seasons in Joes saved game and bred a few gens
of the legends and some of the horses that were already in the barn.
I have to say not too impressed with how they breed they mainly are very averaged only a very few actually
get Frankels or Black Caviars extended bars most have very low reached potential and were unusable for the ck.
i had 1 nice sprinter who i exported to ck and he was no where
near my best sprinters a distance i have spent no time on they are Milers who did not reach mile stamina
i also got 3 nice milers out of which only 1 really performed well in the ck won a few trials but was not markably better than
anything i have bred a couple of trials pictured below.

Have not posted this to fuel another row so please do not post in this thread if you have nothing constructive to say.
i just wanted to stress that the legends (Breeding) on average are no better then what you breed yourself obviously its a huge
shortcut
None of this really matters as any horse with legends in breeding will be detected in any future leagues anyway
