Response velocity tracking

Measure how fast public opinion shifts with real-time velocity metrics on every poll.

The most useful thing a sentiment platform can tell you is not what people think today. It is whether what they think today is different from what they thought yesterday, and by how much. That is the metric that lets a comms team get in front of a story instead of reacting to it.

Velocity is now a first-class metric on every poll. It is computed as the rate of change of net sentiment per hour, normalized against the poll’s rolling baseline. A poll moving by less than the baseline is steady. A poll moving by more is a candidate for an alert.

Where velocity shows up

  • On every poll card in the dashboard, as a small directional indicator next to the sentiment value.
  • On the poll detail page, as a dedicated line on the trajectory chart.
  • In the alert rule builder, as a trigger type that fires when velocity exceeds a user-defined threshold.

Why it matters

A poll that is 60% supportive and stable is a settled question. A poll that is 60% supportive and accelerating downward is a story about to happen. Until now those two readings looked identical in the dashboard. They do not anymore.

Velocity is computed continuously and is available retroactively for every poll in the workspace. There is nothing to enable — open any active poll and the new metric is already there.
