It's not defending itself here, both because I used GLM 5.1, not Claude, and because I was the one who decided to do this analysis, iterated through six or seven different methodologies to try to find the one that was most honest with the data that I had (all of the methodologies showed directionally and often in magnitude the exact same thing, but I wanted to do something that fit the purpose, in consultation with my wife, who, as I've mentioned elsewhere, has a master's degree in statistics), and, of course, I specifically chose all of the metrics and sources for the data.

If you don't want to read the LLM prose, you can just go to the GitHub of my project, grab the scripts, and run the full pipeline. It will gather the data, build the database, and run the analysis from scratch for you, and you can look at the numbers directly. It's all repeatable.
