There's also probably a hundred labs skipping over replication completely to try and beat someone else out on a random permutation of these materials and methods and hoping to get lucky.
Publishing an exact reproduction is difficult, but a new record a few degrees hotter is easy. (And even another variant with a lower temperature and more tolerance for current or magnetic field can be published with the right text.)
Assuming one exists. Assuming it is real.
Abandon the work if nobody can replicate LK-99 within a few weeks and you haven’t really lost out badly.
