I've been so long in dealing with book club thread titles that when I saw this thread I first read it as "2013 Rotating Distribution" and I thought, "Huh?"
Here's my 2013 numbers:
5 star - 7
4 star - 5
3 star - 12
2 star - 5
1 star - 0
However, I list everything even if it's very short. If I removed items less than 100 pages, I'd remove 2 5-stars, 1 4-star and 1 3-star.
That does make me wonder - would rankings averages change if they had to factor in page count? For instance, if one person read a 100 page book rated 1-star and a 1000 page book rated 5-star, in normal rankings that would give their reads a 3-star average. But if page count were factored in, all the sudden their average would jump to a 4.6. I suppose for most people there may not be much of a change anyway.
