I graphed this for myself a while ago in my work as a technical founder of CircuitLab (YC W13): https://imgur.com/37mbya5 https://imgur.com/37mbya5 Two striking findings emerged (and FYI I'm a "frequently commit small logical changes" person): 1. My work patterns seemed surprisingly self-consistent, with a notable gap 2am-10am for sleep and around 1pm for lunch and exercise. (Plus a markedly lower average in the evenings after 7pm for seeing friends, just relaxing, etc.) 2. The intersection between my curve and the window of 9:00am-6:00pm is only 53%. If a "conventional" employer were to constrain my productivity to that window, that's at least some first-order measure of how much inefficiency that constraint would likely produce for me personally -- 47% reduction.
