Essentially the scale jumps up or down by a factor of 10 if any length of the bounding box is streched to 10*currentscale + 10*currentscale/2 or squashed to currentscale/10-currentscale/10*2. In other words, an attempt is made to maintain approximately 10 hashings over each ruler. This need not apply to the "partitioned ruler mode" as the ruler is already subdivided. This is true by default-set to false if many more hashings are needed. Note that in this mode a single minor hashing will be placed between each major hashings whenever a reconfiguration is needed.
