I could be wrong but I believe different TOCs have different marks / grades as to what they consider as enhanced. I think there is a national standard but I’d have no idea what the mark / grade is for that either as when I did my assessments I was just told I’d passed until I failed the VSE. It was with ARL who apparently require enhanced but again no idea what that mark is.
Also worth noting that some TOCs require enhanced passes but I think only ARL and one other use the VSE.
Sorry for rambling on when I could’ve basically said I don’t have a clue
