Regarding the CIV4EraInfos.xml
I remember reading this before too, like if you set itrain to 50% for ancient, it'll mean that itrain will remain at 50% for the entire game.
Not really. I've tried and it doesn't work like that, I'm almost 100% sure. Moreover in the dll there's a function that get your current era if I'm not mistaken and hence uses settings for the era you're currently in.
Edit: it could be like that in vanilla civ, but definetly not in AND.
