a metric like word diversity, or count of 'unique' comments are on my list to test. Tuning and testing is key. This was a very raw model, a very early starting point. Glad you got the file open, many didn't lol, but I needed to do some sort of testing and well thats the tool I know how to use best. Delighted you came by to have a read, thanks for taking the time to review the idea.
