In 1964, the pros had an internal point system on a 18 or 20 tournament basis, with no difference between the status of the events. Many matches and some tournaments, especially on the South African tour late in the year, were not counted. Rosewall, who led the US tour until July 1964, finished on top in a close race under this system. But Laver had a 15-4 head to head, won US pro and Wembley, the two pro biggies, and won 11 events to Rosewalls 10, and if one looks closely, it seems, that Laver surpassed Rosewall with his Wembley win in September and closed out the year with his domination of the South African tour.
Overall a good list, Hoodjem, closely following the Wikipedia list, made by Carlo and others. Some years are always debatable: For instance, i would give Connors 1976 and Borg alone 1978, Newcombe 1971 or Smith alone 1972.
