When Stargate stuck (say) 10% more data into TBS's analog signal by
stashing it in retrace and blanking intervals and the like, TBS's bandwidth
requirement went up zero. Zip. Zilch.

How much does your bandwidth usage on your new miracle boxes go
up if you stick another 10% data stream in there? Probably a measurable
amount more than zero.
