As a rule of thumb, website owners use 10% of served bytes as the inbound
protocol load of sending that data. I think you can assume thats symmetric
for clients so if you request 1Mbyte of data, you probably send somewhere
under 100k to get it. Thus you might expect to be billed 1.1Mbytes. (if the
bill is the addative sum of inbound and outbound)
Beware however that many billing methods count DECIMAL mega and giga so there
are more billable megabytes than show up on-disk where powers-of-two are used.
