While it might not be a record of an experiment, it's a whole lot better in terms of data analysis than just someone's gut feeling. That last one was something I expected much more in the comments where people would just "well duh" this type of publication. At the very least this data analysis shows something with a trace, instead of just throwing an idea out there and hoping someone builds a complete thesis around it and starts experimenting while everyone else is still guessing and having feelings but not getting anywhere concrete.
