I'm pretty confident on this one. Right after shit really hit the fan they published a pier reviewed study showing how the machine could successfully do every test. The paper got ripped to shreds by critics since they used a different sample for each test, and reconfigured the machine in between tests. In a very controlled setting they could perform one test at a time.
