It's not like 100GB is some huge amount of data. It's easy to hit, so if we're judging the overage amount we should be comparing it to the full 100GB, not some made up guy that only uses 10GB. There are users on unlimited consuming many terabytes, and they're not paying all that much more. It's not unfair to anyone if the cheaper plan is able to slowly reach 200GB or 300GB in a minimal-impact way.

Also dropping all the way to 10kbps with enough use would just suck. It's effectively unusable and it would be extreme penny-pinching to make sure the maximum 24/7 user can't squeak out more than 3GB extra on their 100GB plan. You get more variance than that from different month lengths.
