I could live with a cap in the range 180-630GB per month. Seems like their cap may be better than Comcast's!
Whenever I watch Netflix HD my consumption spikes to 8.5Mb/s then after a couple minutes it settles down somewhere in the 6-7Mb/s range for the remainder of the video. I have yet to query my switch at intervals more than 5 minutes while watching a video, but it is on my to do list still.
Yes, if fills its buffer s fast as it can then stops completely. After some time it download at full speed again until the buffer is full. If you monitor per second you see this. Per minute, maybe. At 5 minutes, you would see an average.
