I assume the calculus involved there, regarding the number of keys per node, is only approximate - AFAIK, ever since the appearance of .cdx indices, Fox was compressing them, physically storing only the difference between two consecutive values. Mmmm... it's been a long time since I last looked at the structure of a .cdx with a magnifying glass (i.e. hex viewer), could be it's time again.
