Coding and documentation

29 tasks. March 21, 2026 closed at 20.8x weighted leverage across 528.5 human-equivalent hours in 1,526 minutes of wall-clock time. Supervisory leverage came in at 266.5x.

That is 13.2 weeks of human-equivalent throughput in 25.4 hours. The ceiling was 288.0x; the floor was 0.5x. 22 of the 29 entries came from a single project.

Analysis

The highest factor of the day came in at 288.0x and the lowest at 0.5x, a spread of 576.0 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 120.0 of the 528.5 human-equivalent hours, or 23 percent of the day. No single task dominated the total, so the weighted average is representative.

Supervisory time was 119 minutes against 1,526 minutes of execution, a ratio of about 1 to 13. Supervisory leverage of 266.5x 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.
