Active Diffusion Time Source Scan

spread follows persistence time

At fixed speed, persistence time changes the deterministic active-spread scale. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Two seconds gives four square metres per second

Hold speed at 2 m/s. Persistence time 2 s gives active spread scale 4 square metres per second.

Four seconds gives eight square metres per second

At time 4 s, the same speed gives active spread scale 8 square metres per second.

Six seconds gives twelve square metres per second

At time 6 s, active spread scale is 12 square metres per second. This is a deterministic scale, not a full stochastic simulation.
