Walkthroughs, with the transcript on the page

A video is a bad place to keep an explanation: it cannot be searched, quoted or read with the sound off. Each walkthrough below has a full written version, so the page is useful without pressing play.

What the analysis does, in four minutes

The intended walkthrough: upload a log, read the log-quality score before the charts, check the step response per axis, then read the before/after table and copy the CLI. There is no video file embedded yet — when one is published it will be a privacy-enhanced embed, loaded only after a click, with the transcript below it.

Transcript (written version)

Start with the log, not the tune. The report scores the log first. If the score says the log cannot support a tuning decision, stop and fly a better one. The guides show how.
Read the spectrum before the step. A motor-noise peak and a frame tone are different problems. The spectrum tells you which frequencies are present; it does not tell you which screw is loose.
Read the step response one axis at a time. Overshoot and droop look similar and have opposite fixes. The confidence grade tells you whether the chart is allowed to move gain at all.
Read the before/after table. Every line states the old value, the new value, and the rule and measurement that produced it. If a line does not make sense, do not paste it.
Copy the CLI and change one profile at a time. Fly the verification flight, check motor temperature, then re-log and compare. The comparison is the actual test.

Planned episodes

Reading a step response: overshoot vs droop, with two real charts.
Why a weak step chart is not allowed to raise gain.
From a Betaflight 4.2 CLI log to a before/after table.
What a re-log should prove, and what it cannot.
