Measure one uninterrupted interval

Use the same unit for your observation and target.

  1. Record a starting amount.
  2. Play for a measured number of minutes without spending that amount.
  3. Record the ending amount.
  4. Enter your current amount and the target price from the live shop.

How the estimate works

Progress per minute is (ending amount − starting amount) ÷ observation minutes. Remaining amount is target minus current amount, with a minimum of zero. Estimated minutes are remaining amount ÷ positive progress per minute.

Know when to remeasure

The estimate assumes your observed net rate continues. Upgrades, changed activities, pauses and spending can change the result. It does not predict a door requirement or guarantee a purchase time.
