Performance management systems have always been rigged. Certainly at the last company that both my wife and I worked for. She had to manage a small staff, and come review time, she rated one deserving employee with a 4 out of 5 overall. HR called her in and said, "You can't give anyone a four, we don't do that here." They changed the scores and the employee got a 3 like everyone else. Complete bullshit.
