Relative chat energy, from 0 to 100

The score compares each window with the rest of this VOD. Rapid human spam matters, up to six messages per person and window, but a moment still needs multiple viewers. Known bots and isolated outage messages such as F, lag or stream-down chatter are ignored. Adjacent windows are lightly smoothed.

Chat creates the candidate pool and remains the dominant signal. Speech cross-checks what happened near each reaction; Gemini sees both and keeps 72–74% of the original chat score in its final blend.
