About this task
Rule: All pilots launch simultaneously. 3 min max. 3 flights per round.
The Challenge: The standard 'All Up' — everyone launches together, 3 attempts total. The key decision: stick with the group or seek solo lift. With only 3 flights, one wasted launch means you're already behind.
Decision factors:
- Follow the thermal everyone found, or break away?
- Only 3 attempts — can't afford a wasted launch
- Group-failure dynamics: when everyone crashes, the solo lift-finder dominates
- Reading air independently vs relying on visual cues from other pilots
What the data says: The most common version (3,028 entries). 25% max rate, 17% failure rate. The most normally distributed task — smooth curve with no extreme bimodality. Group dynamics create correlated outcomes (everyone flies well or everyone suffers together).
