Good points, people should see this.
Personally I could do without the swearing though. I get your frustration since you've probably gone through that stuff (and the stuff from the first videos) hundreds of times. However in the video(s) it comes across as if you are putting on a show. It makes you look like an arrogant know-it-all and unprofessional. Tbh - if I didn't know you from years on this forum - I wouldn't contact you to record at your studio after seeing the videos. (Aside from the fact that I'd come in prepared and well-rehearsed anyway but people on this forum aren't the target group for this video either.) Leave me alone with the grumpy guy. I don't want to be yelled at by someone I pay. You know what I mean?
Don't get me wrong you're absolutely write about all the technical stuff but maybe you could do more educational-type videos.
