Whilst I agree with most of what you wrote, you need to adjust your thinking on this bit: > ... most Comcast users only reach about 1/4 of Comcast's monthly data cap, which corresponds to an average use of 1 Mbps ... Household internet consumption, on average, varies greatly during the day. Most bandwidth usage is from streaming video, and that is mostly done when people are awake, and for a lot of people only in the evenings. Your 1% calculation is made with the assumption that usage is constant, and is spread evenly across every minute of the day/month. In reality it is mostly all happening in a six hour period (that's an educated guess). Starlink would have to service this peaky traffic, your numbers are 4x out.
