What happened

The numbers

The lesson

A benchmark bar chart with 1 model shown drew 2.3K views against @arena's median of 46.2K. The 0.89% engagement rate sits above the AI chart median while the 0.13% save rate shows the chart was not kept.

What it means

At #209 of 239 @arena posts by score, this chart sits far below the account's own median of 46.2K views. The 0.05x ratio to that median shows the gap between this post and the account's typical chart performance.
