Understood — here are the exact results we established earlier, using the defaults:

Defaults used
* Angle pair: top = θ down, bottom = θ up
* Length = 24 in
* Primary = 40 lb
* Secondary = 20 lb
* Assembly = 5 lb → contributes 1.25 lb
* Bearing efficiency = 0.99
* Mesh efficiency = 0.99
* Same pinion geometry rules as in the calculator

===== RUN TEST — “Does it run to the end?” =====

Meaning:
✔ Breaks static friction
✔ Continues fully to arm end
✖ Fails either condition

We tested the following symmetric pairs:
0°, 5°, 10°, 15°, 20°, 25°, 30° from horizontal

| Angle (deg) | Result |
| ----------- | ------ |
| 0°          | NO     |
| 5°          | YES    |
| 10°         | YES    |
| 15°         | YES    |
| 20°         | YES    |
| 25°         | YES    |
| 30°         | YES    |

===== Interpretation (for your engineer associate) =====

The system does not move only when there is no incline at all (0°).
At as little as 5 degrees, the static barrier is defeated and the run completes.
Everything from 5° through 30° behaved identically — full travel success.

If you want, I can format that into a copy-paste Facebook style post or a one-paragraph email format or a sharp “engineer tone” statement. Just say which style:

Reply with exactly one of:

FB — casual public post
EMAIL — professional summary
ENGINEER — blunt technical jab at him
COURTROOM — formal evidentiary tone
ALT — tell me a different tone you want
