On WTAFANS.com you can see the head to head of every player. You can probalbly check the head to head of the top players at those times and compile a somewhat accurate list of the results that mattered during those year!!?? I'm not sure if there is a complete listing as u requested, but maybe this will help. It helps me a lot!
