    Ran it through the calculator again http://paxmans.net/performance_calc.php, for the Lightning he gets 8/9 from rated games (Duboudin and Savitha are unrated) for a TPR of 2055 or 2038 depending on method.

    For the Cup it's 3/6 (Bryan is unrated) for a TPR of 1600 or 1603 depending on method.
    The slower I play the better I play, who would of thought?

    Vega doesn't calculate true performance ratings, it calculates FIDE-style performance ratings, which are not the same. (The FIDE/Vega calculations typically go wildly wrong when someone has one or more very low-rated opponents.)

    That explains it, one of Eddy's opponents (played against in both tournaments) is rated a bit under 600

I excluded all his games against unrated players when using the calculator, perhaps vega is treating those unrated players as having a 0 rating?
    Yes, I am sure.

    Thanks for the calculator, Pappubahry - much appreciated (and certainly more useful than questioning whether a disinterested reporter doing disinterested reporting of the vega numbers had reported those numbers correctly).

    Since Duboudin is ACF/FIDE unrated, where did his 1542 rating come from?
    The Force can have a strong influence on the weak-minded.
    Mos Eisley spaceport The toolbox. You will never find a more wretched hive of scum and villainy.

    It was his chess.com Rapid rating when the event was played and was accepted as a reasonable estimate because it was derived mostly from his participation in online events organised for the TCA - and because that was the only guiding info. we had.

    Thanks James for posting the lists. That's the debut for Nigel Lewis in the classic top ten.

    I'm curious what will happen with my quick rating, since the only tournament I played between December and now I had 5/5 vs rated players but 0.5/2 versus unrated/no games (one has a Standard rating)

    Only one classic tournament rated for this period but all the Hobart players around the top ten have gained points. The new top ten is Bonham, Rout, Straton, McMahon, Cohen, Rumley, Nguyen, D Kuzmic, Harvey and Lewis. Cohen, Rumley and Nguyen are all at the highest positions they have been at.

    The new quick top ten is Small, Dyer, Peirce, Ocoleanu, Straton, Rout, Bonham, Amos, Rumley and Lim.
