I stream video (mostly Netfix) 6-8 hours a day. My streaming settings are for minimal data, roughly standard definition, and I use 4-6 GB a day on a 300GB/month data plan. Sometimes I binge watch, might go through 20GB in a day. One month, confined at home in depths of winter, I used 450 GB on my 300 GB plan, got a nasty notice from the provider. Fixed it by turning off HD option and changing viewing habits.
Watching the Olympics as streaming video, you aren't going to get very far with your data plan. You'll be lucky to get one day before going over. Size of the plan is off by maybe two orders of magnitude.
Cost of Intenet connections, for me, is a good demonstration of just how great a bargain is OTA TV, if they happen to be showing what I want to watch. Which is not very often.
I would be looking for the nearest sports bar, to watch the Olympics.
