Correct. Stick with what works. There's no good reason to re-learn a pedal stroke just because you're switching over from a road single to a road tandem UNLESS there is an unreconcilable large disparity in captain/stoker cadence that warrants fitting the stoker with a shorter set of cranks (or visa-versa in the event the stoker is the spinner with the better developed stoke).
