Hello, sorry for the late reply but about your questions:
"Weakness" will decreases the Agility of the Weak character, and like starvation it'll kill the character if he is weak for too long.
If by "Starvation Rate" you mean how often the character are hungry, well there isn't a real difference depending on the character. The only real difference is when Deedee is the Captain. But I haven't really test the hunger in this game so I could got it wrong.
Well, even this isn't really a question, yes! 'll do my best now to add event of 60 Parsecs.
