Experiment: do left hand side spokes of rear bicycle wheels carry driving load (torque)?

An experiment:
Do left hand side spokes of rear bicycle wheels carry driving torque (load)?
Conclusion: total spoke tension change when pedalling with force isn't huge, just about 5% in total, but both left and right hand side spokes carry the pedalling load on modern hubs.
