yeah, which is why I'm not one of those "oh I wish you were a filly" people for most of the time. If it's WW+ I will always prefer boys, since at least they can give me some good show/colour mares over the course of a month. If it's an EEE+ mare chances are she will hopefully bring me ONE EEE foal in her lifetime, but if she isn't one of my prioritized ones, she will get wasted on throwout PPPs all the time.
The "three match" rule is inaccurate. There is no reason for that to be in the guide, just as "RF" and matching guidelines aren't in the guide. A lot of shit here you just gotta figure out yourself
