Let's say the Quad G5 video took 40 hours to make. Especially if time was an issue, he could have spent half an hour to do minimal research, and sacrifice that time from the video's total length. The point is the fact that the video, borrowing the Quad and everything necessarily took hours, some of which could have been used, instead, on minimal, less-than-an-hour research. The video's lack in quality was not a matter of time, but a matter of incompetence.
That's all there is to it. Want truly definite proof? When called out on the mistakes found in the video, he didn't acknowledge any of them. No willingness or concern to do better, or provide clarification, such as claiming there was "a lack of time to do better", or anything even remotely to that effect.
That is not the attitude of someone who produced a low quality video because of lack of time.
