Leisesturm, I agree with you that da Vinci confirms your assessment, and also adds a factor.
So, now I have some questions for you and others about IPS versus traditional tandems.
Let's start with my da Vinci.
If captain (C) and stoker (S) pedal at different rates, then the total power = 100% of the rider spinning faster, right?
If C and S spin in sync, then is the total power 100% C + 100% S?
Do the C & S have to be perfectly in sync to combine power or just close to the same rate?

Now, let's go to a traditional tandem, like the Trek T900 we both have.
If C and stoker pedal at different rates (with C faster), then the total power = 100% C - some factor for C pulling Ss pedals + 100% S?
If C and S spin at equal rates/power, then is the total power 100% C + 100% S?

I am finding this thread educational.
