Some climbing data....

Brian and Janet on Mt Diablo in the Low-Key Hillclimbs: 110.3% of the male single median speed.
Janet on Alba in the Low-Key Hillclimbs: 81.3% of male single median speed.
Brian on Old La Honda at Low-Key Hillclimbs: 131.8% of median single male speed.

Okay: I'll assume the ratio of masses of Brian to Janet is 4:3. Then I should weight their speeds (roughly proportional to power:mass) proportionately. Doing this, using their individual speeds normalized to the median male single speeds, I get 110.2% for the predicted tandem speed. As a tandem they were 110.3%.

Not bad, all things considered.

I was interested to see how out of phase their cranks were: 90°:
