[split] Volvelles or Disks

[Rafal]

This means the glyph you write now is mechanically forced by the glyph you wrote immediately before.

It is empirically deterministic

The problem is that Voynichese is probabilistic and not deterministic.

The letters depend of previous letters but these aren't absolute rules, just tendencies.

You will find a lot of exceptions and uncanny cases for any rule you will say, even for Prefix + Root + Suffix word structure.

If some disks or volvelles were used, they weren't the only thing.
