How is this valuable? People play above and below their rating all the time. It doesn't mean they are sandbagging.
Here's an example. Keep an eye on the Robustness column. Carlos had a stroke. Brooke, Henry, Laurie, and Alfred have no robustness. But you have three players on team Thomas with FargoRates in the 460-480 level that recently won a tournament at the Soaring Eagle Open with performance ratings in the 570-640 range (I did the math) that are performing in our summer league after 6 weeks (~24 games) at the 318-375 level. That's not playing above or below your level. That's clear and obvious sandbagging. But it takes someone like me using AI to pull the facts when the CSI website could just show this information by default and act as a deterrent for this behavior.
This is using the equations
@mikepage has posted online before. A "Performance Rating" is what your
FargoRate would be for a limited set of matches like a single tournament. I've been sharing performance ratings for recent local tournaments. I'm also able to calculate performance ratings for our local summer league. So this is real stuff where losing to a lesser opponent has a big impact and losing to a strong opponent has less of an impact.
Here’s a stunning black beauty Arthur player! If u searching for a genuine player here it is Don’t let this opportunity pass you by
