Yup, about 2-3gb per Netflix movie is confirmed from some searches I did.

So for my purposes (mostly video games and netflix streaming), 250gb per month is generous enough. As long as I don't host torrents, I should be OK.

And they didn't really change the rules on *me*, they started doing it before I signed up, so I went in knowing what the situation was. What I don't like is the inability to monitor the overall household usage unless I install a routing server in front of the cable modem.
