That would then allow utilisation to hit the 80% figure and still support a top tier customer starting an upload without causing noticeable congestion.
40% of 18mbit is about 8mbit, which gives the 10mbit free for a user to max out their upload, one out of 200 users uploading at any given time is hardly a remote possibility.

64QAM upstream channel capacity is 27Mbit, a channel hitting 80% is going to show noticeable congestion regardless of its capacity as it shouldn't be spending significant periods of time at 80%, and as you alluded to below the aim of the game is to ensure that that there are few enough users sharing the capacity that the balance of probabilities are far as usage goes are in your favour, or that historical usage levels indicate that MAC domains have an appropriate mix of users.
While torrents eat 60% of upstream bandwidth way less than 60% of people torrent, many people barely use a GB of upload per month.
