You may possibly have heard me say this at one time or another, but I 
don't know that I've ever run across anything that's absolutely, 
unfailingly, purely binary 100% yes or no. So no, not necessarily. The 
clicks also come and go with humidity changes, as makes sense 
considering the dimensional changes in the wooden under lever, which can 
make the noise source hard to verify.

They aren't all that rule oriented and dependable, in my experience. Not 
good team players. If you glue or swage the leads in the suspected under 
lever and the noise immediately stops and doesn't come back, that was 
possibly it.
