Just say what you think when you see it, I get what you're saying, and I don't even see an issue with nearly any of the text itself in the section, but the terminology, organisation and methodology for each Alien version existing is a mess, even from the perspective of someone who accepts all Alien variation it's not great to navigate.
Especially in comparison to AVPE's design, I suppose simplify wasn't the correct term but it's certainly easier to understand while remaining believably complex, it struck the balance.
And I don't like the suggestions it described on the penultimate page, but that's not much of importance.
