For context on JumpCrisscross's comment in this thread: the 4 hours is between two separate launches on two separate rockets. This is absolutely not refurbishing and launching the same rocket 4 hours apart.
Seems like the actual record for turning around the same booster is 21 days, which is still quite impressive.
