I love the follow-along videos. Not to follow-along to during my workout, but to show me what Coach's expectations of form & tempo are. Having a video demonstrating technique slowly and deliberately is absolutely necessary for a student person to pick up the form; having a "technical notes" video to highlight common mistakes and walk through the nuance of an element is the next step, but then having the final work video showing what an acceptable set of reps is ties it all together.
Coach & GB team: it sounds like you're debating about whether to do follow-along videos for the F3/F4 elements. I hope you at least do a step 9 video for the later elements to demonstrate acceptable tempo of a mastery set.
