As far as I understand it, the detection of higher symmetry is based on the atomic coordinates and not structure factors though (please correct me if I'm wrong here). At least some of the cases for which the deposited structure factors strongly suggest a higher symmetry don't seem to be detected using that papers approach (I can't find them listed in the supplemental).
