It's basically a theme here for me to talk about obscure and practically (spell checked to piratically at first, awesome) meaningless math and numbers, but here I go again. I'm not sure why I do it, but inevitably if I'm looking at a spreadsheet or doing something progressive I begin to break it up and analyze it probably too much.
When I set my goal to read all of Harry Potter within a few months, I set up an excel spreadsheet that listed each book, the page counts for them, and let me input my progress and see % completion for each book as I went as well as the entire series. With 7 books most of which were roughly 700 words, this was a daunting task for me at first but actually went very quickly. I finished a solid 2 months early, which is better than I ever expected to do! After that, Becky challenged me (again, it's always her fault) to do the same with Wheel of Time so that I would be set to read the final book by the time it comes out in late 2011. The pace that needs to be set for that to happen is roughly one Wheel of Time book a month, and so I created a spreadsheet and have even gone one step further and I've begun tracking my progress by date every few days in the same spreadsheet.
The result of this tracking is that I am finishing roughly 1% of the entire series (counting only the 12 books that have been released so far) in about 3 days. I'm currently 42% of the way through the 5th book, and at the moment it syncs up nicely that I'm reading 10% of the book in 3 days that is the same as 1% of the whole series. Right now, including the four books I've finished previously, I am 35% of the way through the entire Wheel of Time series (released to date). When the newest book is released in a week or two that number will be skewed somewhat by the addition of ~700-800 new pages, but that's not a huge deal when looking at the whole. To be more precise if the new book is exactly 800 pages that will only set my series completion back by 2.5% but it will make my overall progression go a bit slower. If I assume that after that I will be completing 1% of the series every 4 days, I'll still be finishing up in roughly 260 days which is well before the 1 year mark.
I'm very happy with this information, because it means I should easily be able to throw in a book or two in the next year that isn't from Wheel of Time and still reach my goal pretty easily. Perhaps I just use numbers and math to make myself feel better?
