15–20 seconds. Time adapts to term length and the depth of the cave.
Start at 10%. Navigation Success is measured against a 100% ceiling.
Fast-answer bonus. Correct within the first 10 seconds: +10 percentage points.
Misses scale. A miss removes 20–30% of your current Navigation Success, so mistakes cost more when your score is high.
