Thanks for the feedback! The zh.wikipedia demo uses a simple method: it averages the previous 30 days and checks whether the current value is within ±10%. As for the zh data itself, starting from late March 2025 it changes irregularly compared to other languages and even to its own 2024 pattern. That usually points to data issues — maybe bots or crawlers — though there could also be another cause.
