Finn “Mischief” Farrer has built a reputation for running detailed simulations of the Valve Ranking System, helping teams and fans understand their odds of reaching the Major based on upcoming schedules and likely results. Now, the British analyst has taken that work a step further by releasing a public tool that anyone can use.
This matters because VRS calculations have long been difficult to follow for fans and teams alike. With Major qualification often decided by a handful of points, a transparent way to model different scenarios gives the community a clearer picture of where every roster stands.
Background on the VRS System
The Valve Ranking System determines which teams receive invitations to Major qualifiers and events. Because the formula weighs match results, opponent strength, and event importance, small changes in a team’s schedule can shift their projected standing significantly. Analysts like Mischief have built independent models to estimate these shifts before Valve publishes official updates.
Mischief Introduces OpenVRS
Farrer announced the new project, called OpenVRS, in a post on X. “VRS is very confusing; it’s closed and it’s not easy,” he wrote. “I want to change that. Introducing OpenVRS: Full auditable sim data, plan your calendar, compare event worth, test roster changes and a lot more.”
The tool allows users to view auditable simulation data rather than relying solely on Mischief’s published conclusions. In addition, it lets fans plan out a team’s calendar, compare the value of different events, and test how potential roster changes would affect a team’s standing.
A screenshot shared alongside the announcement illustrates how OpenVRS visualizes predicted qualification positions. The example shows the projected position range for teams competing for a spot at Singapore, including Team Spirit, Team Vitality, Team Falcons, MOUZ, G2 Esports, Aurora Gaming, FUT Esports, BetBoom Team, B8, Alliance, Astralis, Magic, FaZe Clan, BIG, PARIVISION, IC Esports, HEROIC, Natus Vincere, Nemiga Gaming, HOTU, 1w Team, Luminosity Gaming, and 3DMAX. Each team’s range is plotted against the qualification cutoff line, giving a visual sense of how safe or uncertain their spot currently looks.
According to the same source, Natus Vincere currently show the widest range of any team in the projected November rating, with their simulated position spanning anywhere from 3rd to 53rd. This makes NAVI one of the most unpredictable cases in the current qualification picture, since their final standing will depend heavily on results still to come.
Conclusion
According to Mischief’s announcement, OpenVRS is now available for anyone to use, moving VRS simulation from a closed, expert-only process into something the wider community can explore directly. For fans and teams tracking the road to the Major, the tool offers a way to test scenarios themselves rather than waiting on periodic updates. Given how volatile cases like NAVI’s projected range already show, this kind of transparency could become a valuable resource as qualification schedules continue to unfold.
