Mainly because it was not enough and it has not a follow up resources. Now it's better than when I used to show it, but still not enough. So when people finish they are lost about how to continue, and it's definitely not enough. So I would need to spend a large amount of man-hours to teach it, but if it's just for a couple of people I find teaching them myself, with real-time feedback, corrections and explanations works much better as everyone has different needs.
