The screw is still the worker's job
The Information reports that Tesla turned out several hundred robots a week last month after it moved the Model S and Model X lines to Optimus. The same report names a goal of 20,000 a week. The V3 hand and forearm carry more than 100 screws, and a worker fits them by hand for now.[1]
The weekly robot count does not close out assembly of the hand. The screw stays with the worker. These screws on a new line may be a temporary method; a later fixture may take on the same job.[1]
The lease is not on a customer site
The robots are used internally for specific tasks in limited areas. Tesla plans to lease the robots first and to use the training data it collects.[1]
No lease has reached a customer site. The work that can be measured sits on the line that screws the hand together. The next figure worth publishing is worker hours per hand, not another weekly robot count.[1]
