Hi, If memory serves it's actually slightly more complicated. If you are using loops=<number> then I *think* (you'll have to check) you will find that invalidation happens once per each loop start. However when you use time_based to do the repetition there is essentially only one "loop" (even though the job goes on forever) so loop actions only happen right at the start of the job with that option (that's why I put the scare quotes around "beginning" ;-).
