The authors stress one of the benefits of the PCM method is that it identifies “both expected and underappreciated structures” (line 499). However, the results are not clear about which structures are the novel, underappreciated, or previously unknown ones. The manuscript would benefit from a short discussion or clarification on which individual results from the PCM technique are the most critical or important to the research community and which results simply confirm already known patterns.
From R2:
... the authors emphasize that PCM highlights both expected and underappreciated structures and is thus a helpful tool to develop new research questions any hypothesis. It is unclear, which structures are expected and which are novel or previously underappreciated. Which new findings did this method provide and which additional analysis steps are suggested to investigate the novel findings in more detail?
This is clearly something that we will need to emphasise more
