This tool was designed to help user get an estimated total of their possible bandwidth usage, while
interacting with different elements on the web. The values are examples based on averages using a PC
and are estimates only. The actual amount of data used for the described activity can vary
significantly. Since many activities have many variables that contribute to their bandwidth use,
Sparklight can't give you a 100% accurate value.
