We can discuss subjective 'impressiveness' all day and there is no single answer. Same with some statistics - we can argue over which stats matter more. But for me, most sense is to just look at ATP points, since that's what we use to determine #1 anyway. The way the points are calculated have changed, plus we are not done with this year yet, so comparing totals doesn't work. But what works is comparing *relative* points: How #1 in each year did compared with #2, #3, the top 8, and so on.
Here's what it looks like:
Points earned in 2010 so far:
#1 Rafa = 11,450, #2 Fed = 6,625, #3 Djoker = 5,525, Combined 2-8 = 31,780
So, #1 has 173% of #2, 207% of #3, and 36% of 2-8.
Percentages for historical years:
2009: #1 Fed 10,550, #2 Rafa 9,205, #3 Djoker 8,310, 2-8 44,088
#1 has 115% of #2, 127% of #3, and 24% of 2-8.
2008: #1 Rafa 6,675, #2 Fed 5,305, #3 Djoker 5,295, 2-8 23,035
#1 has 126% of #2, 126% of #3, and 29% of 2-8.
2007: #1 Fed 7,180, #2 Rafa 5,735, #3 Djoker 4,470, 2-8 22,245
#1 has 125% of #2, 161% of #3, and 32% of 2-8.
And now 2006:
#1 Fed 8,370, #2 Rafa 4,470, #3 Davy 2,825, 2-8 19,405
#1 has 187% of #2, 296% of #3, and 43% of 2-8.
So bottom line: Rafa has had an incredible dominating year against the field this year, compared to the last few years. But not as dominating as Fed had in 2006. Fed's point-hogging versus the rest of the top 8 in 2005 is just crazy.
