Only 20mbps?

You don't need DOCSIS 3.0 for 20mbps. Cablevision and RCN have had 20+ mbps tiers with DOCSIS 2.0. My DOCSIS 1.1 Comcast power boost reaches to about 20mbps as well.

Why not utilize the technology for all its worth and start it at 50mbps?

utilize that for 50Mbits speed? then users need to utilize to tune the TCP window size be largely window in order to get benefits of 50Mbits of speed or otherwise if users don't utilized with TCP window size then they are out of the luck unless users are on the typical Vista or Win 7 OS that utilizes auto tune window size.

Short answer: why compete when you don't have to?

Long answer: SL seems to be trying to allow for a lot of overhead on their tiers, so they don't have to sink money into node splits etc. to provide service. If you have 1000 people on a single cable node, there's no way you can ever hope to push 20 Mbps on a single DOCSIS channel. So while 20 Mbps is a conservative number, their network probably can't handle much more than that.

The real kicker here though is the upload: 1 Mbps. Granted, this is better than 768k, but I think SL will have a hard time when Clear WiMAX comes in with that same upload speed on a $35 or $45 package. Suddenlink has tended to be rather ridiculous with low upload speeds though, so this is the rule, not the exception; in some areas (where 8 Mbit or 10 Mbit internet is the fastest tier) residential tiers max out at 512kbps on the upload side.
