Welcome to the forum. The traffic is fairly light and there is a lot of spam, with occasional good feedback, even if it is a bit delayed.
I have not built one, but think I understand how it works. The weight of the pendulum is probably not important since it is converted between potential energy and kinetic energy and back to potential energy with each swing. It is nearly lossless except for air resistance and this is not dependent on the weight.
If the pendulum loses energy after 20 swings, then it seems like there needs to be more weight on the arms. The pendulum pushes the arms and then the arm pushes back for a slightly longer duration. This might take a larger driving weight to lift larger arms.
What experiments have you tried? I am curious as to how the debug is going, since this looks like an escapement that I would like to try to build one day.
