Rankings and reality - are people interested?

Before I was published, and then for a few months thereafter, I was a little obsessed with how my book was doing in Amazon's rankings, and wondering how that would translate to sales. (Not like that any more, no.... )

Naturally, I Googled the issue plenty but I found little hard info, so I was wondering - I now have my first royalty statement, and I have looked at my ranking and the # of books Amazon claimed I'd sold (using Bookscan) over the period of that statement. As a result, I can make a pretty interesting comparison between reality and the rankings.

At least, it's interesting to me. So I was wondering, if I blogged about it, would people like to see how a 20,000k average ranking correlates to sales? Or, if Amazon says I sold XX number of books in a two month period, what does my royalty statement say? That kind of thing?

I know this would be revealing some private info, but I don't much care about that. Are there reasons I'm not thinking about that I shouldn't do this? I think of it as kind of a public services to those out there wandering through the fog, the way I was.

Thoughts?

Mine doesn't break them down much. And it won't be scientific by any means. Just a drop more info for writers starved of it.

I'll try and put something short together in the next day or two. It wont be detailed, more of an overall view. I'll do it on my blog then come back here and link to it.

Quick update. I've written the blog entry but I ran the idea by my publicist and she asked me to hold off until the head publicist returns next week. Hopefully I'll get the go-ahead then.
