Choose a measurable session goal
Set a goal using information you can actually observe: practice the activity, compare a repeatable sample, or estimate time to a visible progress target. There is no verified unlock ladder or rebirth schedule in the public description.
Which situation matches your session?
I am learning
If you are learning the controls, choose a short practice session and focus on understanding the visible feedback.
I can measure a rate
If you can measure a stable rate, record a baseline before comparing another session.
I have a visible target
If the game exposes compatible current and target values, use the estimator with your observed progress per brush and brushes per minute.
If you cannot verify a result
A target without a known unit cannot produce a meaningful estimate. Keep current progress, target progress and gain per brush in the same unit. If the game changes its interface, measure again.
Questions for this task
Should I reset my progress?
No reset mechanic or payoff is verified here. Read the actual game explanation before taking an irreversible action.
What should I do after reaching a target?
Review whether the observation was accurate, then choose another personal goal. The site does not promise a reward for that target.
