Maybe it was the environment, that a lot of these people could be better if supported the right way? Or to say it simply (and please understand I know nothing about you so it is not meant as a criticism of how you personally work), maybe it was because they worked with you? I would also say that throwing x% and hiring again does not work well. The pool you are hiring from is people that are not happy somewhere else. You are not getting a 90% chance of finding a "good" person.
