I beg to disagree. I think high BP conversion rate equals more match wins especially if you can hold serve. To the casual non tennis playing crowd the article may have some merit and interest. One other thing is that we need to focus on a handful of players with formidable h2h against fed, and who are dangerous on his draw, e.g Djokovic. Nadal Murray etc. that should be an indicator of Fed's problems the stats against journeymen don't matter.
