This is a really good question. I actually avoided recording this because I didn't want to depress myself during the writing. I spent a LOT of time on this.
It does, however, come from real-world work. My client projects have been successful from techniques in the book.
I'd need to split hairs to determine what time was spent where and in the end I just needed to write.
It's the same problem with choosing a ebook platform. No tool does you any good until you are actually using it. I'm currently writing in Apple's Pages app because it was the nearest and easiest way to just get started.
The benefit of a product is that it can become many things and the hours put into it can be easily won back with more sales.
