Yearly rankings are the aggregated standings from subsets of matches within the group, including all matches played during a calendar year.
Now is the time to draw up a balance of the year that just ended!
The 2019 subset (and the subsets for all previous years, if any) will be built and processed for all Plus groups created during last year in a few days, as soon as a sizable number of match is recorded in 2020. And the 2020 subset will be built at the same time, together with 2020 Q1 - 1st Quarter and 2020 M01 January subsets!
Of course, each subset has its own ranking, graph, and stats (check 'Games and subsets' widget for available subsets).
Therefore, we suggest you keep recording your matches in your original group, so that you can keep collecting statistical data, enjoying your new year ranking without losing the global ranking (with all-time stats, belts, badges, activites). All rankings (global, yearly, quarterly, monthly) will be updated after every match. You can easily switch rankings in all widgets.
Happy new year, and happy gaming!
