But that's not enough, because this sample alone doesn't explain the extreme variability of other samples. This conclusion is only possible under the assumption that all other samples are bad or incorrectly measured---a highly unlikely event. In particular they were needlessly critical of Southeast University before [1], which reported the increasing resistance up to ~230 K, then a sudden drop til ~255 K, then back to the normalish curve. I previously criticised that the purported "zero resistance" below ~110 K is misleading, while I was unsure about the drop, but at least it does show the completely opposite trend to the PKU result and CMTC should have explained (or refuted) this as well.
