Selection by ratings
The primary criterion for ranking candidates is the Q statistic
Details
-
Subperiods are Sep to Nov 2025, Dec to Feb and Mar to May 2026.
-
The Qstat: The qualifying statistic is Q = (P1 + P2 + 2 x P3)/4 , which is a weighted
average of
peak ratings in the three subperiods.
-
Third peak: You cannot earn the peak in the third subperiod until you have played 50
games rated
by ASPA in the qualification period.
-
Penalty: If you do not earn a peak in a subperiod , your peak in that subperiod is equal
to the
last rating minus 200. This may be applied more than once.
-
Incomplete tournament: If you miss a game for any reason other than an assigned bye, you
cannot
count a peak attained in that tournament for any qualification purposes. Games played will count
towards
games quotas. Ratings will be calculated as usual, with byes and forfeits not rated.
-
Games: You must have played at least 50 games in the qualifying period.
-
Tie breaker: If two players have the same Q statistic, the one with the greater number of
games in
the qualification period is ranked higher.
Players may appeal to CASPA for a special dispensation in exceptional circumstances.
In the event of any unforeseen issue the decision of CASPA is final.
