The same goes for year-to-day list.

For me, it would be interesting to compare those lists with official ATP/WTA ranking, because official ranking favors higher prized tournaments. If we imagine the situation, for instance, that one player wins 2 tournaments, one from 500 series, and one from 250 series, playing against exactly the same opponents on both tournaments, in exactly the same number of sets, he would be awarded double points for the 500 series tournament for exactly equal achievement as on 250 series tournament. Elo rating system irons those differences, taking into account only head-to-head achievements.
But what would the starting points be? Imagine you're at Doha 2013. Year just started. You're calculating the "race" ranking. Federer wins 1st round against....say Tomic. What is their ranking before and after this one match? Something like 1500 --> 1520 for Federer and 1500 --> 1480 for Tomic?
