If you restrict your focus to the mechanical effects, then yes, it's hard to make an informed vote. That's why I recommend you don't do that. Focus on what kind of institution you want Mathilde to create, not what kind of bonus you want to what kind of dice.
I get that, which is why I understand the reason you do not want to give out the information. The trouble is that in this case the mechanical effects inform everything else to a scale out of all proportion to any other choice in the thread. Locked AP for instance would impact every single plan vote for the foreseeable future. That is why we are all playing 'guess the AP number', behind that dry fact is every single action we might want to take and all the fluff that involves.
