Measure one uninterrupted interval
Use the same unit for your observation and target.
- Record a starting amount.
- Play for a measured number of minutes without spending that amount.
- Record the ending amount.
- 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.
