Estimate Steal an Egg treadmill time from your current speed, target speed, and a measured gain sample.
The Steal an Egg speed calculator provides an interactive observed-rate and time-to-target result with target-reached and zero-gain states. This working measured-rate calculator uses current and target speed, observed gain, and sample duration.
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 official product says eggs grow twice as fast; select 2× here only if your current treadmill observation 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 egg growth separate from treadmill assumptions.
Plan a route around the five-minute cadence.
