I did this math for someone in another forum:

Assuming the average data use is 1GB (which according to some cisco article, it was most recently) and that the top 1% use 24% of all data (same source) we can project that the top 5% of all users use roughly 70-80% of all data. Remove them from the sample size, and the AVERAGE use among the remaining 95% is...

310MB.

So yep, you very quickly enter the top 5%.
