Regular candle goals depend on play time and route
Regular mode starts with your current candles, target and typical daily play time. It uses a visible planning curve to estimate a daily amount, then shows the remaining candles and an approximate number of Sky days. The curve deliberately slows near a typical full run because candle collection is not a flat candles-per-minute rate.
Use the estimate to compare routines, not to prove an exact finish date. Realm choice, chevron state, available wax, social stops and missed days all change the outcome. If your normal run is shorter than your best run, enter the normal duration; a conservative input gives a more useful plan than a theoretical maximum.
