[split] (lack of) scribal mistakes / corrections

[bi3mw]

.... the scribe seems to have been like, Uh oh, too many repetitions will arouse suspicion. Better add another stroke to one of those words that makes it different from the others! I think this point has merit.....

I think because you can see the corrections, that would be counterproductive. Thus, one would draw attention to the deception especially because people get stuck with (rare) mistakes. It would be best in such a case, to do nothing and hope that the reader just do not notice.
It is more likely that the author has really made mistakes. Especially because repetitions in the VMS are nothing unusual.
