I have said this before, 1500 hours does not a good pilot make. It's the quality of training, self discipline and type of experience that makes a world of difference.
I have trained cadets with 140hrs that perform better than a FO with 3000hrs. Equally I have had the pleasure of training a ex biz jet chap (1100hrs) who's skills and SA were better than that of 10,000 hr captains!
