`TimeLoopAdaptive` works with the so-called predictor-corrector method. This means that before calculating the actual time step the result is predicted from the past solutions by polynomial extrapolation. This has the benefit of better convergence in case of non-linear problems because the initial guess for the iterative loop is already close to the result.

If $`\|q\| \le 1`$ then the actual time step is valid. In the other case the calculated time step is rejected and must be calculated again with a reduced step size.

For the next step the step size is adjusted to aim for $`\|q\| = 0.8`$.
