The error grows exponentially. For example, for equal-mass triple with Earth sized orbit initially, the prediction limit is just a few hundreds years even if you know initial conditions up to the plank length (LLM estimate of ~135 Lyapunov times).
The uncertainty increases and predictions are reliable only up to a couple hundred years but those hundred years are good enough at any point in time, because you redo your predictions all the time.
This kind of iterative process might yield some insights on how uncertainty creeps into the system.
