Twenty-eight tasks in a single day. The bulk of the work was building out a cloud console simulator from scratch and populating it with hundreds of lab definitions and executors across multiple certification exam tracks. Domain specification generation for a free educational tier rounded out the rest. The weighted average leverage factor hit 98.1x, driven by the initial simulator scaffold at 576x.

Analysis
This was a build day. The cloud console simulator went from nothing to a fully scaffolded application with an engine, four service simulations, a lab runner, and a starter lab in 25 minutes. A senior full-stack engineer would spend six weeks on that foundation. The 576x leverage factor is the highest I have ever recorded on a single task.
The rest of the day was population work: filling the simulator with lab definitions and executors across multiple certification tracks. These tasks ranged from 53x to 192x depending on the complexity of the lab scenarios. The pattern is consistent: once the architecture and conventions are established, stamping out content that follows those conventions is where AI leverage peaks. Each batch of 25-50 labs came with both the JSON definition files and the TypeScript executor implementations, ready to run.
Domain specification generation for the educational free tier accounted for 7 of the 28 tasks. These ranged from 15x to 120x. The variance came from topic complexity: programming language fundamentals (Python, JavaScript, SQL) follow well-established taxonomies and generated quickly. More abstract topics (data visualization patterns, security fundamentals) required more nuanced goal hierarchies and took longer.
The lowest factors were the TypeScript error-fixing tasks at 10-15x. Debugging type errors requires reading error messages, tracing through type definitions, and making judgment calls about the correct fix. Less mechanical, more analytical. Still, fixing 95 type errors across 38 files in 12 minutes is not something a human does before lunch.
The supervisory leverage of 438.5x means that for every minute I spent writing prompts, I got back 7.3 hours of human-equivalent output. Two hours of supervisory effort produced over five months of full-time engineering work.
