There are no rules in what you linked to that would prevent or even deter maximum fines in every single case. The only limits imposed are $10 million for lower level fines and $20 million for upper level (or percentages of revenue, whichever is higher - the static amount will always be higher for smaller businesses).
Edit: to those downvoting this (and all of my other comments) - this comment contains only facts. So please show me where it says that there are circumstances under which they must fine you less than the maximum. Otherwise there is nothing to downvote.
