I did not know about 1-59/15 syntax, this may give me more options... but I was thinking (if there is no other way) to do something like
0,15,30,45 * * * * 1,16,31,46 * * * * ... 5,20,35,50 * * * * 6,21,36,51 * * * * .... 10,25,40,55 * * * * This should give me 15 values and having this pool of values I would pick a random item and assign to a job... Thank you.
