What is the actual bandwith you could use, continuously, given your ISP's bandwith usage cap?

Well said regarding wireless.

You are contending with everyone else that is on your channel. This will most definitely impact your throughput.

If you were downloading a huge file that consumed all your bandwidth and say wanted to watch youtube while you wait, well good luck with that. In networking there is bandwidth and throughput. Bandwidth is the max that can be transmitted down a link. Throughput is what actually gets transferred. Those number are not the same. There a ton of factors that determine what your throughput actually is. Some examples are upstream congestion, latency, and protocol behavior. None of those reasons have anything to do with 'the ISP is trying to screw me'. A lot of it is the laws of physics and TCP/IP protocol stack.
