I've seen a brick and bungee experiment also. I don't remember if there was one or two bricks and bungees. But, I do recall that sometimes you would get small slips closely-spaced in time, and sometimes large slips with longer time intervals.
Mark Zoback and others published a paper on aftershocks of Loma Prieta (1989 Santa Cruz Mountains; I know the regulars know this but maybe some readers do not?). There were left-lateral aftershocks on faults parallel to the San Andreas. The idea (I think) was that most of the expected differential stress was released by the main shock, so that stresses associated with the quake itself could dominate. I would assume this would only have happened over part of the fault. I probably did not read the paper.
