Even if that is true, (and a fact, he), Petes RG results are much more than two times worse than Federers.
Fed's walk to the finals a lot of those years were WAYY easier then Petes.

If those were Pete's routes to the final of the French Open over a 4-5 year period.. Id like his chances at a French Open title too.
