The video makes that appear to be a lot more chaotic that it really is. If you slow the video buy a factor of 7 or 8 that make the video about 1:45 to 2:00 minutes. I realize it is not scientific but that speed appears to be about right, and it looks much more practical.

But, it would only take one idiot to mess up the whole process. As noted above, there are LOTS of those around.
