Where is the basis to this argument? What other magic item have we seen in erfworld that has a limit that refreshes per turn? You're thinking too much about magic and not enough about what is powering it.
Well we know that a thinkamancer can only send so many messages in a turn, so it would make sense that other 'mancies have a limit, so the bracer could well have one too. The bracer was given to him in order to give him abilities he should have had in the first place, like the glasses, so I don't think it would be taken away from him.
But at the same time I doubt he could sit down for an entire turn and just do math, I think that would just be abusing the system.
On another note, am I the only person that thinks this is just a story? We aren't going to see him sit down and work out exactly where the tools are, or when people will attack, and probably not even the cup and ball thing. Why? Because that would be terrible writing, an impossible warlord that can manipulate anyone with math, has every arkentool, and an army of dragons and the undead would not keep people reading.
A lot of the things you guys are asking about have absolutely no use in the plot, and probably don't have an answer. The bracer could predict it's future use because it's useful for the story, and we will see it again when it's useful, not to play theoretical games with what it can and can't see.
