My experience is different. For most students, video doesn’t help them progress nearly as much as direct instruction. A video running quickly through 45 techniques would have less value than a similar-length video that covers 15 techniques. Same without the video.- For some people, they go to workshop to learn.
- For others, they go to workshop to obtain information.
Since I have recorded all my workshop on video, My workshop students all get a copy of that video for further study. At least they will have enough information to work on for the next 2 years.
