Estimate Steal an Egg treadmill time from your current speed, target speed, and a measured gain sample.
Record displayed Speed before and after a known treadmill duration. The calculator divides observed gain by sample minutes, then divides remaining Speed by that rate. It reports target-reached and zero-gain states instead of inserting a site-supplied biome threshold or universal treadmill rate.
Take a short treadmill sample, then estimate time to your own target. The game confirms the treadmill/speed relationship; it does not publish a universal gain rate here.
No universal rate was published on the checked official surfaces. The calculator derives a rate from the gain and sample duration you enter.
That is not assumed. The current official product says eggs grow twice as fast, not that treadmill Speed gain doubles. Use 2× here only if a controlled treadmill sample in your current game supports it.
The calculator reports that no estimate can be made and prompts you to repeat the sample or check the current game state.
Collect a clean speed sample.
Keep the current egg-growth wording separate from a measured treadmill effect.
Plan a route around an interval you observed in the current server.
