If a year is 365 days and each day has 24 hours and each hour has 60
minutes of 60 seconds each, that makes 365*24*60*60=31536000 seconds.
If the stats are in megabits per second, and if you have an average of 1.0,
then 1.0 megabits are transfered in 1 second, 2.0 in 2, 3.0 in 3 and so on.
Keep going until you've reached 31536000.
Divide by eight to get Bytes in stead of bits.
Calculations are done using CDEF. See the various tutorials.
