    "abstract": "For a hidden variable theory to be indistinguishable from quantum theory for\nfinite precision measurements, it is enough that its predictions agree for some\nmeasurement within the range of precision. Meyer has recently pointed out that\nthe Kochen-Specker theorem, which demonstrates the impossibility of a\ndeterministic hidden variable description of ideal spin measurements on a spin\n1 particle, can thus be effectively nullified if only finite precision\nmeasurements are considered. We generalise this result: it is possible to\nascribe consistent outcomes to a dense subset of the set of projection valued\nmeasurements, or to a dense subset of the set of positive operator valued\nmeasurements, on any finite dimensional system. Hence no Kochen-Specker like\ncontradiction can rule out hidden variable theories indistinguishable from\nquantum theory by finite precision measurements in either class.",
