Blue-zone probability chart

Set the current circle, then read where the next one can reach. Contours show where the next centre falls; switch to the survival field to see where a team can stand and stay inside. Both are simulated from a candidate algorithm, not fitted to match data.

What this is. A forward simulation of a published candidate algorithm — the centre-selection routine described in Tencent's region-adjustment patent family — not a model fitted to observed matches. The radius ratio is a placeholder and propagates into every number here; measure it from your own annotated matches before quoting any of these figures. The excluded-edge band is a crude stand-in for the real terrain whitelist, whose shape is map-specific and unknown. Region area is shown next to every probability on purpose: 90% of the mass spread across 60% of the map is not a prediction.
