Sources & Corrections
What's indexed
The database structures publicly documented zero-retention evaluations, starting with Rokslide field evals — mounted-rifle drop protocols with measured zero shifts. Every row is verified against its original source thread before it is published. Community summaries and spreadsheets are used only as an index of what exists; the source thread is always the source of record.
Assessed and not indexed: Backfire's head-to-head drop tests. We read them — but their drop protocol tests unmounted scopes for mechanical survival and doesn't measure zero shift, so mapping those results onto zero-retention columns would misrepresent both the tests and the columns. If a source doesn't fit the stages honestly, it stays out rather than getting squeezed in.

What we add
Structure. One row per eval, one column per test stage, consistent status vocabulary, mount-setup caveats carried as data, and — as the database grows — aggregate statistics with sample sizes displayed in the same breath. A stage the source didn't run isnot tested, visually distinct, never collapsed into a pass. That distinction is the reason this database exists.
What we deliberately don't reproduce
The write-ups. No quoted prose, no republished narratives, no target photos from source evals. Structured outcomes and a link — the testing labor belongs to the evaluators, and the full write-ups are worth reading in a way a table can never replace. No affiliate links appear anywhere in the database; rows link to our own research guides, which carry any monetization.
Corrections log
- 2026-07-17 — zerotech-trace-adv-4-24-2023-rokslide: Database launch note: the community quick-reference PDF originally showed this scope as green/pass, while the source eval documents zero shifts on the 36″ drops in all three drop evals. The PDF's maintainer corrected the entry in December 2024 after a community callout. Our row carries the per-stage record from day one — this collapse of incomplete or mixed results into a single green cell is the failure mode the stage columns exist to prevent.
Disputes and annotations
If you ran one of the indexed evals and believe a row misrepresents your results — or you want a caveat attached — use the contact page. Evaluator disputes get priority: it's your labor. If an evaluator asks for their results to be removed from the index entirely, we remove them and log the removal here.
