I ran this by da Vinci and received the following response:
"On our tandem, the person pedaling at a slower cadence is not contributing, nor are they robbing power from the other rider. On a traditional tandem, if one person does not keep up, the other rider is pulling there(sic) legs around and being robbed of power. Todd Shusterman"

On an IPS tandem the 'slower' cadence will not provide a proportionately reduced level of power to the drivetrain. The slower cadence will provide ZERO power to the drivetrain. But IPS sure is popular.
