Nailed the issue to the floor

This one perhaps combines  “nail down”  or “nailed it” (get it right) and “take the floor” (one’s turn to speak).  On the other hand, perhaps “wipe someone off the floor” (beat someone up) could have been part of the equation?  The context in which I heard it was someone saying that the person really was accurate, as in they “nailed it”.   “Nailed the landing on the floor” (gymnastics) seems the closest, though Martin Luther’s nailing of the 95 Theses to the church door could have been swirling in this person’s subconscious.  Free association is such a personal thing, don’t you agree?
