They stay the same, unless one of the horses belongs to your friend. Then the percentage will be a bit lower, but otherwise it doesn’t matter whether you pair two Tier 3s or a Tier 3 and Tier 4. If you own two Tier 3s yourself, I’d use those and not borrow the Tier 4 from a friend. However, if you own a Tier 4 already and are looking for another one, try to find a friend with opposite gender Tier 4 and breed that with your own Tier 4, so you’ll be guaranteed to get a Tier 4 foal out of it.
