Check whether the error during evolution scales proportionally to the scaling of the center.

The exponential decay function is dependent on the initial value and needs to be scaled accordingly. Decided to focus on a simple constant dynamics to see if there is any odd behavior.

Using the circle-unstable example, realized that the error roughly scales as expected. Going to check with a clean exponential decay function.
