In Response To: XG PR data (Iancho Hristov)

I assume Iancho used the Match Play Performance that shows on the profile summary page. Please, Iancho, crrect me if I assumed wrong.

This value is simply the calculation of the Elo based performance based solely on the results of the matches.

For instance you play three 11 point match , win 2 and lose one. It means your perforance is 219 elo stronger than the average of your opponent elo.

However, this is not as simple as I assume Iancho did not input elo for each player (it's not online games). In that case XG uses for the player's Elo the one determined by the analyze.

The elo system used does matter in the final display (but not in the calculations as we are using there only Elo differences).

The match play performance has a HUGE volatibilty. By going to the "player" page of the profile it shows the luck corrected performance (variance reduction) which is more reliable. However on such short samples it is still quite volatile.
