Hi Wade, this looks great! I gave Voltmeter, Randal, and Distiller a go and they all produced clean, easy to understand reports. This product actually comes at a great time because I was just about to get rolling on some A/B testing and SEO tweaking of a site of mine.
One weird quirk, on the Distiller page, when I came to that page from the Voltmeter, I found the site url I was checking was populated over the top of the instructions in the input box. (Win 7, Chrome 4.0249)
