I'm somewhat surprised that your tandem climbing speed would be slower than the speed of the slower of the two of you alone. I guess if you have two riders that are pretty evenly matched on w/kg, the efficiency disadvantages result in the slower speed. And there's no real averaging effect.
For us, we definitely climb on the tandem slower than my single bike speed, but faster than my stoker's. In other words, for us the averaging effect is greater than any efficiency losses.
