Hi I've been watching, but not downloading, TV shows online legally through the company that broadcasts the shows websites and through Foxtel Go. I would like to know the average amount of gigabytes for each hour of watching so I know how much of my data allowance I am using up. Thankyou in advance

PS I understand the quality of the show and its format of whatever will alter how much data is being used but I'd just like a range of gigs or the average amount of gigs that will be used.
