PPP foals lower LB ratings if there are a lot of them. And PPPs don't always reflect stud quality. It's literally how the game works, after the first few breedings a stable does for a month, they're almost always going to get PPP foals regardless of how good the match is.
Just because a stud produces PPP foals and drops because of it doesn't mean that he doesn't deserve to be there what if the mare has bad production or doesn't match him at all you know
Void, mass breeding usually ends up in PPPs anyways. Doesn't matter who the horse is, if a stable breeds to them over three times and it's not one of their first few matches, the foal is has a very very high chance of being PPP, even if it was a cross between the #1 mare and #1 stud..
if a PPP foal lowers the LB rating I don't want to breed to that stud. I'm not going to FR a perfectly good PPP foal that I can use as a show horse especially if i paid a lot for the stud fee
