From what I understand, this mod doesn't change the random distribution itself, it instead sets the lowest parent stat as a minimum for the RNG, per stat.
My suggestion is to maybe add a mod option to change the minimum value used for any given horse stat, between the lowest parent stat, the highest parent stat, the mean average between the two parent stats, and just having it off. It could add a way for the player to balance horse breeding how they want, for example, by specifically having health scale better per generation and nothing else, or by keeping speed at vanilla RNG and everything else scaling at least at the average parents' stats.
