[Article] update to Zattera's slot machine

[oshfdk]

Currently my best Zattera model, Zat+, beats Loop-Lay in terms of Nbits, but for a coverage of about 80% versus 100% for Loop-Lay. However due to the fat tail distribution of Voynisch words with potétial scribal errors, 100% coverage does not make much sense. I think we should settle for a much lower cocerage and optimize  Nbits from that.

I really have no opinion about the best coverage. Personally, I think the grammar should reproduce all words (maybe with the exception of those with really rare characters like v), otherwise it's not a grammar of Voynichese, but a grammar of some subset of Voynichese, and all conclusions made based on this grammar should carry this footnote with them. I think the main idea of loop grammars was to handle all or almost all words while keeping the grammar size manageable.

Would be good if Mauro could comment on this one. While I use other people's grammars occasionally to check if some of my ideas are obviously bonkers or not, I'm not in the grammar business myself, so to speak. To me a grammar is not a statement of what happens in Voynichese, but rather a statement of what doesn't happen in Voynichese.
