However, there is debate about the features of the manuscript which Rugg's suggested method was not able to emulate. The two main features are lines showing different linguistic features from the bulk of the manuscript, such as the Neal keys, and the statistical properties of the text produced. Rugg argues that these linguistic features are trivially easy to hoax using the same approach with a different set of tables, and would add about five minutes to the time to produce each page; the counter-argument is that this makes the hoax too complex to be plausible. Regarding statistics, Rugg points out that text produced from the same set of initial nonsense syllables but using different table structures shows widely different statistical properties. Since there are tens of thousands of permutations of table design, he argues that it would simply be a question of time to find a design which produced the same statistical properties as "Voynichese". Whether or not this would prove anything useful is another issue, since it could either be used to support Rugg's argument, or dismissed as coincidence.
