This may be a nitpick, but how can something be "fairly deterministic"? Is it possible for there to be degrees of determinism? I would consider determinism to binary, either something is deterministic, or it is not. If a thing cannot be demonstrated to be deterministic 100% of the time, then by it's very definition it is non-deterministic. By that logic, I would actually conclude that the entire universe does in fact behave deterministically. If it didn't, then I don't see how science would even be possible.

I was avoiding an absolute statement because macroscopic objects are entirely capable of behaving in unpredictable ways, however the odds against are so high that the chance of this happening is infinitesimal.
