said by 18286719:whatever channel widths are being used, the max should always be used, as with increased width, there will always be increased bandwidth, for example my cable provider only does 4 3.2Mhz wide channels for upstream, while it seems like optimum uses 2 6.4 wide channels, 64QAM at 3.2 is 15 megs per channel, 64QAM at 6.4 is 30mbps a channel, what needs to happen is that cable providers need to invest in cable plants that can handle upto 1Ghz, some cable plants can only go upto 750Mhz, while probably about 90% throughout north american have a 850Mhz max, imo would be done want make channels smaller we wanna increase available bandwidth by adding more frequency 
Also along with more frequencies, spread them among the users on the node. At the current time EVERYONE on the node gets the same set of frequencies which causes congestion. If you had (lets say) 16 frequencies for download and assigned 8 of them to each user on the node so no user had the same 8 as any other user on the node, you would be load leveling the usage on a frequency between different sets of users.
