Skill and popularity ratings

I downloaded a very popular fan made mode called The Game Changes Now, based on when hulk hogan and Bischoff joined TNA in 2010. I had some questions around the popularity and skill ratings.

WWE’s most popular star is John Cena and his popularity ratings are at mid 80s. You then have people like edge, Shawn Michaels and Randy Orton around the 80 mark, cm punk etc in the mid 70s. Is this accurate? Would one not expect Cena at the peak of his popularity to be in the early 90s? Perhaps symptomatic of the lack of popularity in wrestling as a whole at that time.

More baffling are the skill ratings. Shawn Michaels’ selling is around 89, his psychology is 80 etc. Cena and edge have similar skills in the 70s. What’s the logic here? If Shawn Michaels doesn’t have a psychology in the late 90s, who possibly could?!
