21 tasks. February 26, 2026 closed at 46.3x weighted leverage across 249.5 human-equivalent hours in 323 minutes of wall-clock time. Supervisory leverage came in at 172.1x.
That is 6.2 weeks of human-equivalent throughput in 5.4 hours. The ceiling was 200.0x; the floor was 10.0x. 18 of the 21 entries came from a single project.

Analysis
The highest factor of the day came in at 200.0x and the lowest at 10.0x, a spread of 20.0 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 40.0 of the 249.5 human-equivalent hours, or 16 percent of the day. No single task dominated the total, so the weighted average is representative.
Supervisory time was 87 minutes against 323 minutes of execution, a ratio of about 1 to 4. Supervisory leverage of 172.1x 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.
