I've been accused of being low level in that (if that should be an accusation and not just information) more times that I can count now (ok it's 5). The problem is that that addon does not automatically update the progress of people (you have to re-download it on a new version and half the people seem to not understand that) and it's also very incomplete because it does not cover well what it claims to cover especially because in several occasions it fails to report the main's progress and the alt may show low experience because of that.
