Then it would be the world's most efficient arm-power assist. However
extatic their owners and regardless of the great workout, I gather the
Thys Rowbikes are no faster than merely leg-driven hpv's. Probably our
heart & lung system provides a limit to the total wattage of arms and
legs combined. 

I rode an armpowered trike once and it went very well for about a km,
then I found out my arm muscles were not trained for endurance. First
time I had spaghetti arms instead of - legs.

It's another fascinating aspect of the Python setup that without any
mechanical complexity or weight penalty one could deliver arm assist for
a short anaerobic outburst of acceleration or a short climb. In city
traffic I use the hamstrings for that trick.

Still it's a great experiment, you could shelve your prototype until you
master a normal centersteered bike - sounds like a feat in itself
already - and then try again? You might want to reverse the push-push
movement into a push-pull one though. 

Good luck with your next iteration of Python - the first real HPV Open
Source project.
