She/he wrote "one and five" instead of "one in five" as the context suggests. In other places he/she may have commited the same error.
I noticed that too. However, I recognized it as a speaker error and not a transcription error. If the court transcriber wrote down 'and', it is because 'and' was the word used by the speaker.
In some transcripts that I have read, the court transcriber will put in brackets the word 'phonetic'...meaning that the word is written as spoken. So a court transcript disregards even correct pronunciation - they use the word as it is said.
As I said before, a person makes many errors in spoken speech that are rarely picked up on if we are just listening - our brain makes the corrections for us when we are the listener, but when the spoken word is written down, the speech errors become evident.
I noticed that the whole thing is in video too. Is the stenographer allowed to see that video to correct obvious transcription errors before printing and distributing the final product?
I believe that with video taped proceedings, the video is used to supplement the transcript in order to increase accuracy. An accurate, word for word account is the objective of court transcripts.
