Methodology / version 0

Rules before results.

Entries are observations, not predictions or financial advice. The criteria are recorded before outcomes so the ledger can be audited on the same terms over time.

Pre-registered HIT criteria

HIT criteria v0 rating count reaches ≥2.0× baseline AND absolute gain ≥50 by D+21, OR ≥3.0× baseline by D+42

Boundary cases are recorded as MISS. This conservative treatment prevents ambiguous outcomes from being promoted as successes. Misses are published in the same format as hits.

Criteria changes are versioned and never applied retroactively. A call keeps the criteria version recorded when it was opened.

Corrections and source record

Corrections are appended with timestamps, never silently edited. The source record uses Apple's public iTunes and RSS endpoints, with snapshots recorded daily. Every velocity claim names both timestamps that define its interval.

Conflicts

We may hold interests in competing apps. Conflicts are disclosed on the relevant entry so readers can evaluate the observation with that context.
