I'm using methods appropriate to that low amount of data, first of all. Second of all, since I'm only trying to show there's no evidence for the anti-AI hypothesis (not disprove it, or prove the null hypothesis), that's sufficient in itself. Also, I wonder why nobody said things like you're saying ("there's too little data to tell") in response to all the absolutist claims that AI caused rsync to get worse?

At this point, you're just positing Russel's Teapot: you'll keep assuming more and more of the code was "secretly" Claude when there's no evidence for it and no reason to think so, just because you've started with the assumption that Claude makes things worse and you want to find a way to prove it.
