A post is shown to a small test pool first. If that pool engages above a threshold, the post is released to a wider pool. If it doesn't, distribution stops.
- →Test pool 1: ~3% of your followers + a small stranger sample
- →Pool 2 (if pool 1 engages): wider stranger sample
- →Pool 3: For You feed — only the top 1% of posts reach this
- →Velocity matters more than volume — early reactions outweigh late ones
