More experiment/test on utilizing the hollow, solid & center-heavy, implement it to the swinging weights & rolling balls.
- hollow rolling ball takes longer to lift the weight up, or roll down.
- with center-heavy ball, has a faster reaction to lift up the weight.

Although the rolling ball (or swinging weights) can be configured (hollow, solid, center heavy etc) to gain faster/slower rolling down rate, but theoretically speaking, timing is not really an issue for the overbalanced wheel.
When the wheel is unbalanced (one side heavier than the other), the wheel can take either a minute to balance itself, or an hour to accomplish the same task; it doesn't really matter unless for some efficiency purpose etc.
When the ball rolls down, it can also either take a minute to roll down & lift up the swinging weight, or take an hour to do so. It doesn't matter how long it took to roll down; what matters is it can achieve rolling down & lifting the swinging weight up.
When doing the wheel design, the concept can either be
1. fast rotation/spinning but unstable
- too fast a spin, the wheel will be experiencing the centrifugal effect;
- weights within the wheel will go haywire, very difficult to get the timing right to achieve some particular task;
- small-diameter sized wheel & huge-diameter wheel tend to behave differently, due to the inertia properties, so maybe the design may fit smaller wheel, but not for big size (or vice versa)
2. slow rotation and stable
- weights & wheel can take its own sweet time to accomplish its task

For overbalanced wheel, it should be the weights (ball & swinging weight etc) that determine the rotation of the wheel, not the other way round.
For slow rotation of 5RPM & slightly faster rotation of 15RPM, the balls still can roll down the slope. The rolling down action of the ball can cause a shift of torque increase/decrease on the left & right side of wheel.
But for fast rotation of 30RPM, it take around 2 seconds per 1 revolution of the wheel to push the balls to the edges; all the balls within the wheel would not have the time to roll down. At this situation, it is the wheel controlling the weights.

Checking on the balance between hollow, solid, & center-heavy balls on the see-saw. All the balls weigh the same, with same distance apart.

Comparing the difference between a wheel with only balls, and a wheel with balls & swinging weights
- change in the symmetry of the balls
- position of ball being risen up (and vice versa)

Comparing the difference between a wheel with only solid swinging weights, and a wheel with different type of (hollow, center-heavy, center-light etc) swinging weights. The weight ratio of swinging weight to ball is 1 : 1
- change in the symmetry of the balls is the same
- position of ball being risen up is the same (and vice versa)
basically no difference
