^^In the weekly ranking lists on the ATP website players on the same points share the same ranking number.
That's why I was unsure whether there's any tiebreaks.
So, thanks for the clarification.
Apparently they just intend to keep things simple on their website.
No, they don't. The same ranking number is shared only by players having the same points, points earned in MS/GS, number of tournaments, and points breakdown for each tournament they earned points in. I'm glad I could help and I hope you understand how this goes.
