That is domination, but Federer took 23 consecutive sets of Soderling, between Halle 2005 and USO 2009, and we all know what happened this year at Roland Garros. Nothing is a given.
It's a long-term ownership. These numbers are incredible, I've never thought that Federer used to own Soderling so strongly in that period. But, as you said, this year RG proved that every embarrassing streak can be turned around.
As to Roddick, his poor streak against Roger doesn't look that bad compared to Soda's.
