Everyone in life has disagreements, petty jealousies, things they struggle with in other people. The beauty of the question, Would you work with her or him again?, is that it specifically doesn't try to disentangle those things––because to a productive team the quality its members' relationships with each other as important as the quality of their work. If one or the other is off, it's not necessarily anyone's fault, and it may not even be cause for termination. But it's as good a metric as you need.
But it's utterly foolish to winnow on a percentage basis. You'll break up good teams and prevent better ones from forming. You'll destroy morale. You'll encourage a leadership culture of cutthroat sociopaths whose success is at best tangentially related to the quality of their work. Do not do it.
