We acknowledged the limitations. Our methodology was reviewed by three outside experts, and the results were also reviewed. They confirmed that these are the limitations. However, in our study, we also addressed some of the limitations of other projects previously. I mentioned, for example, using real processes, real candidates, real applications, rather than fictitious ones, in some cases, where it was just a paper exercise. We've gone beyond some of the limitations, but there are still some limitations in terms of our methodology.
