Dear John & Jennifer,
It looks like there is something wrong with the accounting figures. 
The total sessions duration was 13968 seconds. If you deduct both comm. wait 
time and idle wait time the amount of seconds for the 'real work' would have 
been 13968-13086-816=66 seconds!
Looking at the accounting figures the comm. wait time is way to high. I think 
this amount is not correct, otherwise you would have been able to send 943.3 MB 
in 66 seconds while waiting for the rest of the time (13902 seconds)!
Kindest regards,
Eric van Loon
