Yes, but that's thinking practically. This thread is about the mathematic pedantry of actually figuring it out.About Tycho and stress tokens. As soon as you have more than five stress on him you might as well forget about ever having having him stress free in that game. So while the number of stress he can have is potentially infinite, I would quite frankly stop caring and just consider him permanently stressed from that point forward even if I only used green manouvers. Easier on the mind ar least.
I'm a very practical person.
Besides we already have the mathematical answer, it's an infinity sign.
