Note that Salvo also writes (in LIGO P&P comments):
I am a bit concerned about the discussion of my paper, and in particular the idea that might be conveyed, that I got different results because I did something wrong.
In reality, I think the difference might be explained by the fact that my approach was a bit more general, since it assumed that either channels are followed. By contrast, if I understand properly (~line 100), you are assuming that all signals come from the same channel, and you focus on the odds between that channel and the others.
Thus, my ~100 events for ~10% uncertainty refers to a situation where both channels happen, and one measures the branching ratio.
I also considered a situation similar to what you have, Fig 2, where all signals come from the same channel, and there you say that after a few events the odds are already in favor of the right model at >3 sigma (black line) level for most catalogs (and after ~20 events for all catalogs). I think that plot represents a fairer comparison with your results.
Another important factor, is that your test is based on chi_eff, while my test was based on individual spins, which are estimated less well.
