PR size distribution

What it measures

The weekly mix of PR sizes — XS / S / M / L / XL — by share, using a canonical size that combines lines changed with a per-file weight.

Why it matters

Small PRs review faster, merge sooner, and break less. The size mix is one of the strongest levers a team has over its own flow.

How to read it

• A healthy mix leans toward XS/S; a growing XL share predicts slower reviews and more risk.
• Size here is canonical (lines + file weight), so a many-file PR counts as large even if each change is small.
• PRs too wide for coupling analysis (more changed files than the coupling cap) are listed in this panel's drilldown, so very large changes stay visible even when their internal coupling can't be computed.

Anti-blame

Size shares are team-level. There is no per-author size ranking.
