So, of I understand correctly, just because one, five, or ten reports of LK-99 lacking superconductivity doesn't mean that lk-99 can't be a room temperature superconductor, the issue is that there isn't a lot known about why it's superconductive and the specific configuration of atoms required to express superconductivity under ambient temperature and pressure. The process for creating it isn't an exact process and as a result, it's hard to control and ensure that the final structure is correct.
Am I understanding that correctly?
Edit: this also makes me wonder (as a non-scientist) if most conductors could be superconductive at room temperature with the correct atomic structure, but due to technological limitations and a general lack of understanding, scientists are having to brute-force superconductivity via extreme pressures and/or temperatures. Hopefully, however, even if this is shown to be too difficult to be consistently replicated, it'll lead to the discovery of more easily replicated materials.
