The "definition" being discussed is only the electrical connection speed. The actual information delivery speed can be anything a huge, abusive company wants.
What matters is the delivery speed. Supposedly the speed of the connection I am testing is "25 Mbps". SpeedTest.net says the speed is more than "50 Mbps".
The actual information delivery speed measured by numion.com is:
Surfspeed inside United States: 239.24 (29.90)
Surfspeed average (worldwide): 198.64 (24.83)
Surfspeed outside United States: 187.24 (23.40)
A local city leader told me it costs "$400,000" to get elected. Any government that requires leaders to spend huge amounts of money to be elected isn't actually a democracy.
