Welcome to our community, and thanks a lot for your constructive feedback! Rick and Gary tried to find a good balance between explaining things and doing things. Watching a video without following along can help you understand the concepts the respective instructor is teaching. Once you know what to expect from a lecture, following it will become much easier.
If you still feel that something is not clear or needs to be explained in a better way, don’t hesitate to ask your questions here in the forum.
