You can't really be dense enough to think that the racks from two different people will be more similar than the racks from only one person, particularly when one of the two people is known for their ability to manipulate the rack and may have a totally different goal in mind for their racks than the other party does.
You put your offer out specifically because you believe FargoRate is inaccurate, and you wanted a way to offer evidence of that by playing someone higher ranked so that if you beat them it would be evidence to help support your contention. The point you and some others that are a bit slow still seem to be missing is that you are proving nothing about how accurately FargoRate has your or Siming Chen rated if you play only one set. You are proving nothing if you play a game that she doesn't even play. You are proving nothing if rack manipulation can be a factor. If you just want to gamble, by all means do it however you want. But if you want to try to prove something about FargoRate, which was your entire point, then you are going to have to play many sets of a game you both have experience with and in a way that pool skill alone decides the winner and not rack manipulation/reading, or wearing somebody out in a format they have never played, or anything else besides pool skill.
