Steinway Duplex Placement

[Richard Brekne]

Grin... nothing like cutting through the back and forths and just 
answering someones question. That said, these tables are contingent upon
the actual speaking lengths being what they are supposed to be. The idea 
of the duplex('s) was to configure some pre-determined fractional
relationship to the speaking length into the back and front lengths, yes ?
