Considering how the large corporations easily reach the annual cap (currently $6.5 Million per year until at least 2015), the footnote that the 10% maximum increase in royalties does not apply to the cap is a bit disconcerting.
Ah, that explains how the cap has managed to go from $5 to $6.5 million (a 30% rise) since the last time I looked at it, which certainly wasn't 15 years ago.
