Yes, some finger combinations are interesting dexterity challenges (varying among individuals, too), which is why the hysteresis/expectation setting of what's up or down can be important when using it for communication (outside of 132 of course, which is usually pretty obvious). I vaguely recall having at least one drunken conversation with an electrical engineer about what the "voltage equivalent" was for various finger positions might be and what your finger logic gate would need to accept to properly determine finger binary state.
