Maybe a more effective measure would be to take an average or rankings points, then write down the ranking of the player who would be at those rankings. For example, with federer:
This way, the significance of beating a top ten player (Robredo) has more weight than the fact that Ancic had players ranked in the top 200 instead of Federer's top 100, since both players probably have almost an equally low chance of causing difficulty for a top player. Note however that they are close because Massu + Berdych about equals a Robredo plus a low ranked player. This way, the higher ranked opponents dictate the strength of draw calculation. In otherwords, the difference between 110 and 100 should be less than the difference between playing 20 vs 10, and this rankings based calculation does that. I don't have the time or will do to the others, but feel free to do so.
