The research for 1979 is almost done. The mathematical model has been expanded to about 350 players right now, I have the ranking system and calendar all confirmed, will give you the weekly rankings as soon as satellite data is finished extrapolating for the other remaining players.
Sorry for the month-long delay. The final pass of the 1979 rankings will be made tomorrow. The delay was caused by the ATP website change (of course).
Now that 1979 is complete, I will move on to 1980 and 1981, which are the "dark years", years in which more than 90% of data is missing from the ATP website, and where there is a low chance at the moment of reconstructing the lower rankings (below 300).
