I think the Custom Properties solution is actually better than simply offering a "distance traveled" option in the Property Test. A full-history dependent option like that would be somewhat limited in its application. For example, imagine an actor setup where I want to measure the distance traveled from the last landmark reached, rather than since particle birth...well now the generic solution can't be used at all. Allowing the user to save the distance traveled per-step to a channel of their choosing, a value which can be reset or modified and then later measured easily, would be more useful.
