7 tasks. July 13, 2026 closed at 10.5x weighted leverage across 51.5 human-equivalent hours in 293 minutes of wall-clock time. Supervisory leverage came in at 71.9x.
That is 1.3 weeks of human-equivalent throughput in 4.9 hours. The ceiling was 21.8x; the floor was 4.0x. 7 of the 7 entries came from a single project.

Analysis
The highest factor of the day came in at 21.8x and the lowest at 4.0x, a spread of 5.5 times between the two. That is a wide range for a single day, and it usually means the day mixed mechanical work with work that needed real judgement.
The largest single entry accounted for 20.0 of the 51.5 human-equivalent hours, or 39 percent of the day. No single task dominated the total, so the weighted average is representative.
Supervisory time was 43 minutes against 293 minutes of execution, a ratio of about 1 to 7. Supervisory leverage of 71.9x is the figure I find most honest, because it measures the hours I actually spent rather than the hours a machine spent on my behalf.
Every figure here is recorded at the time the work is done rather than reconstructed afterwards. The human estimate is my own judgement and carries the uncertainty that implies; the minutes and tokens are measured. The full dataset, including this day, is available for download.
