Myth: one viral post resets your account to a higher tier

Myth: one viral post resets your account to a higher tier
Viral spikes don't lift the baseline. n=240 accounts post-viral (1 post >10x median), 60-day follow-up.

— Reach on next 3 posts: 1.3x median (small halo)
— Reach by post 6: back to pre-viral median
— Follower retention from the viral spike: 38% at 30 days

The feed doesn't 'promote' you to a new distribution class; it re-bases per post. So what: virality is an event, not a status change. Convert spike traffic fast or the baseline absorbs it within a week.
