I'd be really interested to know what kind of work this analysis is done on. Is it manual labor? Or repetitive data entry? Or writing code? I'd be interested to see a breakdown between these different categories. On this note, does anyone know the original paper where those graphs came from? I clicked through to the linked paper at the end, but no such graphs appeared.
