Grand Piano Action Regulation

This video shows all the steps I took to regulate the action of my C5 Yamaha grand piano. My problem with the piano was a lack of dynamics and some notes occasionally not playing so my primary focus was the blow distance, let-off and drop. The dampers and strings seemed fine as it had been a well maintained instrument. Prior to attempting this I watched all the available Youtube videos on the subject to learn how the action worked and what steps were required for its regulation. Some videos were extremely helpful including those from howardpianoind, Piano Technicians Tutorials and coby jay. The Pianoworld forums also offered a wealth of useful information. While studying the process was useful nothing replaced practical experience to really understand what was going on. I hope my experience can be useful for anyone contemplating to attempt something similar. I'd appreciate any constructive comments on errors I may have made or how I could improve on what was done.
