Exactly, which is precisely why a tuned rear duplex system is impossible to
keep in tune without manually manipulating string segment tensions
(assuming correctly positioned aliquots) with every tuning (referencing
produced pitch comparisons from speaking length and rear duplex as tension
indicators). So if the tuned rear duplex can't stay tuned without manually
tuning it each time, and nobody on the planet that admits it is actually
doing that, and if the tuning of the rear duplex is critical to the
proposed enhanced sound it provides, how can it be that any tuned rear
duplex in any piano out there is doing what the proponents claim tuned rear
duplexes do?
