How it works
Rate novelty
An unfamiliar pattern or library takes longer to review than one that matches existing code.
Rate risk level
Payments, auth, and data integrity changes warrant deeper scrutiny per line than cosmetic ones.

Frequently asked questions
Why does novelty affect review time so much?
Reviewing a change means both understanding the approach and verifying correctness — an unfamiliar pattern adds the extra step of understanding the approach itself, on top of checking it.
Is this estimate precise?
No — it's a rough planning estimate to help you budget realistic review time, not a precise prediction. Actual time varies by reviewer familiarity with the specific codebase.
Should I skip review for low-risk, small changes?
The estimator will suggest a quick review even for small low-risk changes — 'quick' means budgeting a few minutes, not skipping review entirely.
How is the estimate calculated?
A base rate scaled by lines changed, then adjusted by multipliers for novelty and risk level — transparent arithmetic, not a black-box prediction model.
