Review the visible assumptions, enter only observations from your own run, and treat the output according to the stated confidence boundary.
Sanity Scenario Simulator
Model plain subtraction from your own displayed Sanity and observed loss assumptions, with every result labeled as a scenario.
The result does not identify a visitor, predict randomness, or establish an official game formula.
Why every value says scenario
The checked official material does not publish an exact Sanity loss per mistake. The simulator therefore starts with your displayed value and an observed loss that you enter. It does not claim those inputs apply to another run or future update.
The arithmetic
The tool multiplies your observed loss by the possible mistake count, subtracts that total from the current displayed value, and floors the projected display at zero. The arithmetic margin remains visible so you can see how far the scenario passes the exhaustion point.
What it cannot predict
The simulator does not identify a visitor, estimate a probability, model random events, or guarantee an outcome. Use the Visitor Tell Tracker for the separate evidence checklist.
