I think I can go back a few more years. I will post the final results as soon as I can. I am certain that 1981 was the final year and that the results did count for the WTA rankings. I think Rene Uys got a ranking after playing this series. She went on to reach the R16 at Wimbledon in 1985, but like many other SA players, she retired very early (she was 20 or 21).
