I have direct knowledge of the following situation. A 4 star girl beats a 5 star in a 4 hour marathon. She is exhausted but agrees to play the following round against a 1 star who had a walkover in the previous round. The 4 star is up 3-0 but cramping badly. She has to default. Her TRN ranking goes down 30 spots because she lost to someone 700 places behind her. When the new star rankings come out she has lost a star. She appeals to the folks who run TRN but they will not overule the loss, despite the fact that the winning player did not win any games. Now, some colleges will not consider her because she is a 3 star, not a 4 star. Hard to believe this story but it is true.
