Default Re: The Rankings Database

I have managed to reconstruct the 1973 original rankings system with maximum fidelity possible, given that the error ratio for it was estimated at 43.5%. This system accurately gets the YE Top 10 right for 1973 with minimum differences in points and gets a lot of the other players right as well, but there are major differences to the official, which will be cataloged as inconsistencies in the way ATP calculated points as tournaments were counted differently for different players.

The system has been extended to the period 1970-1973, and 1970-1971, previously available here, have been recalculated. You will notice some differences than before, including the fact that John Newcombe gets to be YE #1 in 1971.

Here are the number 1 streaks I got until the end of 1971:
