Thats a good video.
I did not see if you are using a recessed/floating set up of the non recessed.
If you are using the non-recessed, I usually tighten the claw and springs until the floyd is securely touching the body. Obviously you will not be able to pull up on the bar. As a side, with a set up like this is do put a small piece of adhesive felt (the little dot stops you can buy at and hardware) on the underside of the floyd where it touches the body. I do not want METAL/WOOD contact. you can tithed more if you want. The more you tighten, the stiffer the bar will feel. Its all personal taste.
If it is a floating system, I tighten until the body of the guitar and floyd ad totally parallel. I am sure the video outlines that
