Karen Corr has played everybody. Siming Chen has played Karen Corr. Therefore you have a pretty accurate idea how Siming Chen plays against all the people that Karen has played (and all the people that they have played against and so on) with just that one connection. To use a specific example, let's pick Mika. Since you know how Karen does against Mika, and you know how Siming does against Karen, you can pretty accurately deduce how Siming would do against Mika just from that one connection. There is usually more than one connection though and Siming has probably play several or many people that have played Mika so you can be even more precise about how she would play him even though one connection was really all you needed to know with a fairly high degree of accuracy. And you can also know how Siming would play against all the people Mika has played, and all the people those people have played, and so on. In these ways there is a massive web of connections between everybody that plays pool and everybody can be accurately compared to everybody else.
And this is the problem I have with Fargo rate that I'm still trying to wrestle with.
To say Karen played Mika is not placing it in the right context. She most likely played him on the joss tour.
When Karen defeated Earl Strickland at the Turning Stone Classic in the quarterfinals, I watched her charge through the field for 4 days, and then go through the one loss bracket which means more matches played (and remember, this is wooden rack, opponent racks and winner breaks). It was an example of her persistence, fitness, and skill that she could get there. When she took down Earl, at that point, on a Sunday at turning stone, that was a HUGE accomplishment.
So to say, Karen beat earl, and Simeng beat Karen, therefore Simeng would beat Earl is not only cheapening what Karen did, but it's frankly misleading to the entire world to where folks believe Simeng is as good as Earl (because Fargo Rate has them identical)
Let's put it this way, Ko pin Yi played at Turning Stone and didn't even make it into Sunday. That's a difficult tournament and Karen has performed well in it, there are times she doesn't do so well. But she plays in it and Simeng doesn't.
How would Simeng fare? We will never know until she plays.
But if Simeng only matches up against Karen in tournaments with magic rack and alternating break, how can any hypothetical of Simeng versus Thorsten or Earl be taken seriously when she doesn't even compete like Karen.
That's where I'm still not all in with Fargo. To lump all pool matches and outcomes together and derive results without proper context is just not valid in my opinion.
