The site and data normalization are great. The problem is that applying the phrase "best case scenario" is simply false, and it is just a distraction that was not necessary on the site.
Amortizing my entire data usage over my entire cell plan (which includes talk & text), costs me literally $0.001/MB.
You should not present $0.24/MB (US|Prepaid) as the "Best case scenario" when someone on a standard AT&T plan pays 240x less.
[0] for lack of a 'better' word. better being mostly subjective.
