In the video/PDF from "Data pipelines with Google App Engine" Brett puts "now / 30" into the task name noting that he will explain the reason later, but somehow he never does. :)

task_name = '%s-%d-%d' % (sum_name, int(now / 30), index)

Do you have any idea about the reason? Does it have anything to do with the 7 day period in which one can't re-use task names?
