There are definitely corrections in the VMS. How many mistakes there are (and uncorrected mistakes) is hard to say, but it is somewhat consistent in many ways.
It's actually fairly simple compared to natural language. The same "phrases" over and over. It's harder to make mistakes when there is so little variety.
I'm reluctant to hazard a guess as to what the error rate is, but as a guess based on my subjective impression after creating four transcripts, I'd guess maybe a couple per big-plant folio and perhaps up to half a dozen on the pages with dense text. This is absolutely a guess.
