The absolute size of the spec is not a reliable criterion: tue extra 
bits might be well-meaning nice
tutorials for example.

Instead, something like cyclomatic complexity might be more appropriate: 
go through all the
normative text and count every branch word like "if", "and" and "or". 
The greater the absolute
number the more complex the technology; the greater the relative number 
compared to the
file size the more complex the text.  (There are, of course, more 
serious metrics than this,
but you get the drift.)
