Kind of on-topic - I’ve puzzled over why the ‘drunken walk’ multi step dither was ever required. Is it to mitigate the chance of the guide star being lost if a large jump was made in one go - so by making multiple small steps the guide star(s) could be retained until threshold was reached.

It seems to me that a single random jump (random direction) to threshold is actually the same as multiple random steps (drunken walk) to threshold.

Thanks
