Seems like there are two different senses of "reproducibility" happening here: * the developer variety: "running the same code produces a bitwise-identical result" * the scientific variety: "repeating the experiment produces the same result" The second one is much broader; a lot of the work in science is documenting what factors are relevant in "repeating" an experiment: a result which could only be obtained with one exact piece of apparatus would be dangerously close to being irreproducible. Similarly, the idea of "the same result" is subject to interpretation - for instance, measuring the muon lifetime by timing decays in a scintillator should produce a result close to the known value but it can't produce the same value every time since it's a fundamentally random process.
