andrew I hope you not been serious.
They dont need to reserve it and you know that.
even leased line providers dont reserve 100% of bandwidth but they still guarantee 1:1 usage.
The guaranteed speed is probably a % of my estimated speed.
Whoever decided to offer it, probably realised it wont cost anything if at all, they simply provide enough capacity that the vast majority of the time they meet the target speed, in the event an outage or something else prevents the throughput there is probably still a small chance people will notice and even then a smaller chance someone will bother to complain and get it enforced, even if it went all the way what will sky do? maybe refund a month's subs
