According to the formula below, the value for GUFI is not proportional
to the number of words analyzed. Doubling the length of the passage
that is analyzed doesn't double the number of words per sentence or
double the percentage of complex words, although both terms might depend
on both the length of the analyzed passage and which passage is chosen.
Increasing the length of the passages analyzed should tend to decrease
the variations between the GUFI's for different passages in the same
work by the same author.

<snip>
GUFI = {(words/sentence) + [100 x (complex words/words)]} x 0.4
The formula can be easily modified to produce a [GUFI] with any
length sample. Simply multiply the standard result by 100/(words in
sample)
