# YouTube Growth: competitor teardown and video plan

Observation date: 2026-10-02

## Decision
Test a visible diagnosis before introducing the repair steps.

## Compared evidence
Breakout ratio = first-N-days views / median first-N-days views of the other same-channel, same-format videos in this input. Three baseline videos is a minimum calculation rule, not statistical validation. This is descriptive, not a forecast or proof of a title effect.

| Video | Channel | Days | Views | Baseline n | Median | Ratio | Source |
|---|---|---:|---:|---:|---:|---:|---|
| Find the noisy brake | Fictional Bench Workshop | 7 | 3600 | 3 | 1200 | 3.0 | https://example.com/videos/b4 |

## Evidence limits
Input sources were supplied by the operator and were not fetched or independently authenticated. Competitor CTR, retention, revenue, ad spend and audience fit are unknown. Public lifetime views cannot establish first-N-day performance. Use saved contemporaneous observations or a permitted analytics export; otherwise collect a prospective cohort before scoring.

## Packaging experiment brief
Audience: Independent bike-shop owners making practical maintenance videos
Viewer problem: The rider cannot tell whether brake noise needs an adjustment or a part.
Reference: Find the noisy brake (https://example.com/videos/b4)
Transfer hypothesis: this reference suggests a question to test; its result does not transfer automatically to this audience.

Title A: Find the brake rub before you buy new pads
Title B: Three checks for a noisy bike brake
Thumbnail A direction: Original close-up of the contact point, with one labeled arrow.
Thumbnail B direction: Original image of the wheel and a small inspection checklist.

Opening: Play the noise, show the contact point, then say what will be checked.
Evidence to show: Record the sound, close-up of the rubbing pad and the safe adjustment. Use our own footage.
Payoff: The rider can distinguish this demonstrated rubbing case from cases needing a mechanic.

## Test and human handoff
Primary metric: Owned-channel watch time per impression in a controlled packaging test; retention is a diagnostic.
Review date: 2026-10-16
Keep topic, audience, content and observation window consistent where the test allows. Record exposure and traffic-source changes. Review owned-channel retention for expectation mismatch; do not infer why a competitor won. A thumbnail image is not generated by this tool.
Owner must check the claims, sources, image rights and content promise, then choose a packaging version. No publishing or paid generation is performed.
