Single Leg Gallows

wouldn't that then require a reason (e.g. subject matter) for the opchedy/okechedy word type to be so predominantly on the top row?

Good point.

Every option has its problems though.

For example, why are only k or t that are not followed by e replaced by f or p ?
And why are these predominantly on the first rows?

I don't remember exactly the details of Lisa's statistics, they will play a role here.

The whole thing is of course quite complex, and that is why I am not in favour of drawing quick conclusions.

Just imagine the possibility that e is a null character.

Now ignoring the fact that this would bring the A and B languages quite a bit closer together, for the question at hand the whole premise changes, or in fact disappears.

There are just too many variables.
