> I'm not going to be stupid and try to "uncap" my modem to get more speed

I think this modem "uncapping" thing has mostly been an urban myth. Maybe there were some really early cable modem systems in the 90s where that would have been possible, but AFAIK with DOCSIS the speed is regulated by the CMTS [0], not the modems.

It depends in precisely what CMTS is running, what firmware it has and the ISP's willingness to replace/upgrade old hardware at great expense.

At the last telco I worked for we had about 12 CMTS's, and 2 of them were holding up a bunch of upgrades because of their age. One of the things they specifically couldn't do was provision the speed of the individual circuits.
