Only percentages of correct guesses were given, which are quite strange - they do not correspond with whole numbers. For instance, 8 grey artefacts were guessed to be GDE, and according to the authors they were correct with a 32% accuracy. This would mean that 2.56 pieces of obsidian were accurately predicted in regards to their sources. One can not analyze 2.56 pieces of obsidian, and even if one can, why would you? ",
