Attention acceleration is the rate of change in attention, emphasized by Breakflare over static hype level.
A coin can be loud but fading. Acceleration flags rising narratives earlier.
In research workflows, Attention acceleration is usually interpreted with Mention velocity, Hype momentum, Hype score, and Breakout Score™ rather than as a standalone signal. Acceleration often matters more than absolute mention counts. Loud but fading hype is a different setup from quiet but rising chatter.
