- Adopted variant C in the study card →
r5-e63307b6d523“adopt variant C: Loose billows: irregularly gathered folds, vertical at the top and curving gently below.”
I took C in the card. Now slow the whole ripple to about half speed, keeping everything else exactly as it is, and show me it really moves about half as much.

I’ll halve all five time rates—edge motion, fold gathering, billowing, and brightness variation—without changing anything else. Then I’ll compare motion over the same interval and check that the slowed version at 4 seconds matches the original at 2 seconds.

Done—C now runs at half speed. Only its five time rates changed; colours, folds, stars, sky fade, and black hills remain unchanged.
Measured frame-to-frame change over equal intervals:
| Interval | Before | Slowed | Ratio |
|---|---|---|---|
| 0–1 s | 1.2076 | 0.6065 | 50.2% |
| 1–2 s | 1.2107 | 0.6040 | 49.9% |
These measure average pixel-colour change, not physical displacement. Halving every time rate also means the new animation at 4 seconds reaches the original’s 2-second state, visible in the previews.
The starting frame is pixel-identical. Compilation and checks passed without warnings.
