They've had T on the ATP rankings list site for ages (if you go back and look at old dates, they're there).
But I've noticed a lot of them recently too, SC, way more than normal, and I was wondering if that was to do with the new system kicking in over the past few months? Not sure quite how that would effect it but is that possible?
With some 70 players on 4 points as is Patrick, there are bound to be a lot of ties. I'm inclined to agree that it is a result of the change in the rankings system, bringing a lot of M15 one-pointers into the equation. i must admit though, I don't look at the ATP rankings site, as other sites are much easier to search.
