The Scout Hike & Herbie
Ten hikers, ten natural paces, and accumulating variance on the trail to Devil's Gulch.
Run the experiment: Each hiker’s natural pace fluctuates ±15% each round, while the person ahead sets a ceiling. Put Herbie, the distinctly slow hiker, first to keep the line together — or shuffle the line to watch it stretch. Click a trailing hiker to sprint, or use Pause lead to stop the front and let the troop close ranks.
Natural paces: 9 × 3.8–4.8 · Herbie 3.2–3.6
📖 The Story Behind the Simulation
Chapter 11 · The March Begins
Alex Rogo volunteers to lead Boy Scout Troop 10 on a 10-mile hike to Devil's Gulch. He calculates that with an average troop walking speed of 2 mph, they should easily arrive by 3:00 PM.
Chapter 12 · Dependent Events & Gaps
The fastest boys surge forward, but Herbie falls behind. Gaps grow and the troop stretches over a mile long. Alex realizes the trail spread represents inventory (WIP), and independent pace gains never overcome dependent delays.
Chapter 13 · Bottleneck Breakthrough
Alex discovers the solution: put Herbie at the lead to pace the entire line (Subordination), and distribute the heavy cans and gear from Herbie's backpack to the other boys (Elevation). The troop stays tight and arrives early.
