    Pet Weight: Measured Growth Estimate

    Enter two observations of the same pet with unchanged boosts. This projects the measured kg gained per age; it is not a verified game growth formula or trade valuation.

    Example: 1.00 kg at age 1 and 1.20 kg at age 11 gives 0.02 kg per age. Continuing that rate to age 21 gives 1.40 kg. Remeasure after a boost, mutation, or update changes the rate.

    XP Time Planner

    Estimate time to a numeric XP target from your observed gain. Use XP values on the same scale; the planner does not convert age or levels into XP.

    Formula: remaining XP ÷ (observed XP gain ÷ observation minutes). A gain of 100 XP in 5 minutes is 20 XP/minute; 800 XP remaining takes an estimated 40 minutes at that rate.

    Egg Hatch Time Estimate

    Enter the base duration and a continuous speed increase. A 50% faster speed means dividing time by 1.5, not subtracting 50% of the time. One-off time reductions are not modeled.
