Now throw in some standard oversubscription math, and you're at 40¢ per user. 625 simultaneous streams can probably serve roughly 6,250 customers, given that half the customers don't use Netflix, and the half that do, use it at different times of the day.
Also the proportion of customers who needs 4k as opposed to 1080p is negligible. Most consumers don't even have equipment capable of displaying 4k content.
Netflix in 1080p uses 4.22Mbps or sometimes 7.15Mbps, so we're now at 15¢ per user.
