I made a long time 460KB/s constant rate uploading, after 5 minutes, the avg rate was 231, I got the full value 459 until the first 10 minutes was over.
I think the average rate should be always approximately equal to the constant rate in this case.
What is the reasonable time interval for the calculating of average rate? Start form the time when you launch the real-time monitoring page? or, the constant 10 minutes?
