I wonder if this takes into account multitasking. If I poop for 1 hour while reading HN, I can't just add the two percentages separately or the total will exceed 100%, so I have to count the 1 hour twice to normalize. If I do this every day, I get that I spent 1/25 of my time reading HN; however, it's really 1/24 of my time (since pooping is essentially automated away). Same for washing dishes etc. Could be interesting to add a field for simultaneity and then removing the "boring parts done while doing fun parts" bits to gain another point of view.
