Not counting radioactive decay as a physical process because you've chosen to define physical processes as deterministic is some intriguing mental gymnastics.
> Theoretically all physical processes are predictable, but in practice there is a limit.
So you defined away quantum effects as 'not physical', which most people would not agree with. How do feel about the theoretical limits on measurement accuracy that also negate your claim?
But for the context of the physical processes the OP was talking about those effects are not significant and so I excluded them.
