  FIDE Rating Bug Still Biting

FIDE Rating Bug Still Biting

02.06.2013 /   Andrejic, Vladica (2199)

FIDE remains adamant on ignoring the elephant in the room and is obviously unable to fix the bug in the rating lists calculation.

14.04.2013 /   Andrejic, Vladica (2199) : Rogulj's Blitzkrieg: A Long-lasting April Fool's Joke or a New Rating FIDE-ology?
16.05.2013 /   Andrejic, Vladica (2199) : Correct Rating is a Rare Thing

FIDE remains adamant on ignoring the elephant in the room and is obviously unable to fix the bug in the rating lists calculation. FIDE has published new rating lists for June 2013 with the same errors that keep on piling up. What's worse is the simple fact that this is no rocket science, but a very basic mathematical operation of adding two numbers.

We have already published a warning that FIDE software has a bug that keeps failing to properly add the total change of rating points from the processed rating period to the old rating. This problem exists exclusively on Blitz and Rapid rating lists in cases where someone played more than 35 games in a rating period.

Once a phantom quota of 35 games is exceeded for any given rating period, the player's award is either a surprise mystery jackpot or downgrading of his/her rating. FIDE is still quite happy since no-one has reached the magic plateau of 2900, so who cares that IM Branko Rogulj has been strapped of 32 Blitz Elo points.

This time we have 23 players with more than 35 blitz games played in this rating period, and only one with more than 35 rapid games. Needless to say - in all 24 cases the calculation error that I've kept warning about is still present. Enjoy the following tables with concrete figures:
