The Dota 2 PRO-teams ranking is based on their performance over the past year. When compiling the ranking, a sum of points for achievements in tournaments and a team's current form take into account.
When calculating points, we analyze the final results of each tournament played by a team for a year. The amount of points depends on its date and importance. The less time has passed since the end of a tournament, and the higher its level, the more points a team gets.
We take into account the results of matches for the last 3 months. Also, it has a reduction factor, which means the last matches have of higher priority.
It is all based on a core of three active players who should be playing together lately. If all these players join another organization, then all the points they have also transfer to it.
The team's rating will recalculate after the first match played with the new roster.
