I would like to solve the following task ... (see below patch)

The circle area is calculated, and so is the mouse drawing speed.

How do I end up controlling the speed of a metro in the following way?:

No matter how big the circle, I would like to end up with the same speed, if I draw at the same speed.

--> something like draw speed divided by circle size ... ?

If you mean that you want to retain the same rotational speed (rotations per unit time), that means varying the velocity of circumnavigation as the radius changes. Here's an example that might be helpful. (Set the rotation rate and the radius, then turn on the metro.)
