Internet connection question?

[kyle]

I have "high speed" DSL from Windstream.
I pay for 3 MBps. I download around 200-300KB/s always. Windstream says even if I pay for 3MBps, the area that I'm in dictates how much connection I get and how demanding the area is.

My question is.. Windstream says they are upgrading their stuff and it will allow us to upgrade from 3MBps to 6 or 12MBps for an additional 5$ a month at the end of this month (March 31st)

Can I assume I will get an insanely low DL speed, albeit slightly more if I upgrade to 12MBps?
IE: 200-300 KBps out of 3MBps paid for
How many KBps(Or MBps) out of 12MBps paid for?
I'm sure theres a ratio involved, but I can't come up with it.

Thanks a lot!!
Yeah, the "high speed" was supposed to be sarcastic

So I can expect ~30% of what I pay for? Even 3MBps out of 12MBps would be a MASSIVE jump over 200KBps.
Oh. Now I feel dumb lol. Thanks Tom and Shadow!
