Once we get Netflix, and the UK is a priority market for them to move into, things will change a bit. We benefit from iPlayer and other things in the interim though.
Keeping upstreams forcibly below 40% utilisation is silly, 10Mbit up on an 18Mbit channel is fine depending on circumstances as previously discussed repeatedly. There are uplifted areas with over 200 modems on a single channel running just fine.
The next iteration of traffic management you will find much more to your liking though Chris
