Paraphrasing: He explains that the reason that they had no faithful validity is because the dispatcher might have been looking at one of two clocks. That the two clocks were not necessarily synchronized. And that if one got more than one or two minutes off, it was adjusted accordingly.
That means that the tolerances for being off were one or two minutes. However, it doesn’t preclude the possibility that they were more accurate than that.
Nope.. no need to paraphrase and muddy the water. We don't need your version of what he said, when Bowles's own words are perfectly clear;
So, under no circumstance could you put any stock in the real world time references by the belt because there were no time references on the belt; they were only spoken times, and those spoken times had no faithful validity... - James C. Bowles, Communications Supervisor of the Dallas Police Department.
I ask again, who are you and what do you know that Bowles doesn't to disagree with this clear cut statement?
Btw you seem to ignore the fact that the original recordings were made by voice activated equipment, reducing the evidentary value of the recordings/transcripts even further.
