It might be because your using something else.
Maybe you have Teamspeak Open etc...
Like if I was downloading at 950kb and I started to web search it would drop because the speed would have to be divided.
So, I have BT open and d/l speed is slow (90KB/s) so I type into google "Test for bit torrent" throttling then after browsing the web (not testing tho) I see my B torrent reached 650 Kb/s 0.0 wtf and this happend before btw in my country and state throttling is illegal, is it true coincidence or luck?
Most likely you just connected to better peers. Derp.
