When downloading a file, the indicated download speed seems to be the one of the last packet received - ignoring inactivity in between packets. Sometimes, the dowload speed sticks to, eg. 100 kB/s, while evidently nothing is coming in. The pause isn't reflected in the next update either. 

The result being that the 'minutes remaining' can be very much in error. Just now, each 'minute remaining' was taking actually 4.5 minutes!

Reproducible: Always

Steps to Reproduce:
1.download a file from a not optimal source
2.check the 'minute remaining' and speed
3.
Actual Results:  
'minute remaining' doesn't increase if incoming packets are spaced, and d/l speed isn't reduced.

Expected Results:  
Values should be correct. I'd suggest updating the stats by a timer, instead of by incoming events.
