(2) Steps and input are often omitted during the making of movies for the sake of brevity. Describing each input parameter on a form would make the movies exceptionally long and thus a Thus a model developed by the user based on the video may differ from the one shown in the Watch & Learn.
(3) The structures used in the movies do not necessarily represent real structures and are often simplified so that the user will it will be easy for the user to focus on the features and capabilities of the software, and not on which input value to use. It is for this reason that most models in the Watch & Learn videos are often derived from simple templates.
(4) In some cases, the models used in the videos may appear to have "counterpart models" documented in greater detail in written CSI documentation. However, you should never try to correlate any model depicted in the video with a similar model described in the documentation. The video may skip some steps or alter values to make the model simpler or more didactic. In addition, the model itself may evolve over time, but the video typically depicts only the initial version of the model. Verifying and reshooting Watch & Learns for each model update would require substantial resources which is not justified. Again Again, these movies are meant to be qualitative demonstrations and purposefully do not clearly explain or show all the input and output values.
