And if you click "Download usage details", you get a csv of daily per-service usage data.

I'm sorry I didn't specify. I know how to check my usage, but my "next bill estimate" is only 11 cents. My total ends up somewhere between $1-3.

Hmm - maybe download your csv data and see if it reveals anything? It could be some kind of rounding. There's also http://www.windowsazure.com/en-us/support/understand-your-bi... which might hint at something.
