  Achieving fault-tolerance will require a strong relationship between the
hardware and the protocols used. Different approaches will therefore naturally
have tailored proof-of-principle experiments to benchmark progress.
Nevertheless, repetition codes have become a commonly used basis of experiments
that allow cross-platform comparisons. Here we propose methods by which
repetition code experiments can be expanded and improved, while retaining
cross-platform compatibility. We also consider novel methods of analyzing the
results, which offer more detailed insights than simple calculation of the
logical error rate.
