I disagree with two things in that table regarding vav:
- The Tiberian pronunciation is unknown whether it was [v] or [w].
- In Mishaic Hebrew, there is already some confusion between bet and vav, showing that they were pronounced the same (at least by some people) at the time.
If I understand well, "bet" and "vav" are sometimes confused with each other? Like the verb "to write", you mean that it can be pronounced either "katabti" (like in Arabic) or "katavti"?
