Very true. I think this shows some basic flaws in the ranking system. Regardless of his absence he should never have been ranked so low.
I beg to disagree. The ranking system is quite good, and in general all critics of of it that I read give me more reason to believe it is very good.
The case in question in fact is simple. Federer was not playing tournaments, so there was no way to know how well he could play. The ranking system is cold, but fair. Of course one would expect that a top player would return after injury playing better than his ranking indicates, but:
1) First, this is not a given. Other players returned playing bellow average. You can not use Federer as a standard. And even he could have returned playing worst. He earned his points the hard way, and that is
exactly how it should be done. Every number we see after his name now is surely fair.
2) Anything other than a ranking system such as this introduces a completely unfair level of arbitrariness. For how much time a guy out for injury would keep his position/seeding/whatever? 3 months, 6, one year? In the mean time, what the
whole rest of the field does? No matter what they do or how well they play, they cannot earn that spot.
In other words, if the guy is not playing, his level can not be assessed. So whatever ranking he gets is arbitrary and (here comes the bad part) subject to be viewed as an injustice. Thank heavens there was no such a thing prior to this AO. Had Federer received a #2 seed and won people would credit his title to this for ages to come.
I know it gets frustrating sometimes, but this comes from the nature of the game (player´s levels oscililate due to a lot of reasons), not from the ranking system. The ranking is not there to
predict how good people will be playing, it merely assumes that, on average, the players who amassed more rankings points on the current "running" year are playing better than the ones who amassed less. Day in, day out, most of the times the higher ranked player in fact wins, so we have dozens of daily indications that the ranking system is actually good -- even if we generally forget or ignore that.
