What toelva said! I definitely added a week or so of work by doing all the design myself. Writing... if I focused, I could write another book in two weeks of full-time work (maybe less) but the issue is getting distracted, or taking the time to research, etc. Since the work was spread out over a year with a lot of my time focused on my startup or personal stuff, it's really hard to estimate, apologies.
Of course, I can't answer for limedaring but I write software ebooks too. For each ebook, it's between 200 and 300 hours for writing, editing, designing, researching, etc
