By doing this, total scattering rate including this self-scattering, is constant and equal to, say, .

The computer time used for self-scattering is more than compensated for by the simplification of the calculation of the free-flight duration.

For the bliss of the deep abode is not lightly abandoned in favor of the self-scattering of the wakened state. '

By random selection, if self-scattering is selected, k' after the collision is same with k and the carrier continues flight without perturbation.
